Heat tolerant phytases

Abstract

The present invention relates to heat tolerant phytases and DNA sequences which code therefor. The phytases are useful in hydrolyzing phytate to inositol and inorganic phosphates. The phytases are valuable feed additives.

Description

BACKGROUND OF THE INVENTION

Phosphorus is an essential element for the growth of all organisms. In livestock production, feed must be supplemented with inorganic phosphorus in order to obtain a good growth is performance of monogastric animals (for example, pigs, poultry and fish).

In contrast, no inorganic phosphate needs to be added to the feedstuffs of ruminant animals. Microorganisms, present in the rumen, produce enzymes which analyze the conversion of phytate (myo-inositolhexakis-phosphate) to inositol and inorganic phosphate.

Phytate occurs as a storage phosphorus source in virtually all feed substances originating from plants. Phytate comprises 1-3% of all nuts, cereals, legumes, oil seeds, spores and pollen. Complex salts of phytic acid are termed phytin. Phytic acid is considered to be an anti-nutritional factor since it chelates minerals such as calcium, zinc, magnesium, iron and may also react with proteins, thereby decreasing the bioavailability of protein and nutritionally important minerals.

Phytate phosphorous passes through the gastro-intestinal tract of monogastric animals and is excreted in the manure. Though some hydrolysis of phytate does occur in the colon, the thus-released inorganic phosphorus has no nutritional value since inorganic phosphorus is absorbed only in the small intestine. As a consequence, a significant amount of the nutritionally important phosphorus is not used by monogastric animals, despite its presence in the feed.

The excretion of phytate phosphorus in manure has further consequences. Intensive livestock production has increased enormously during the past decades. Consequently, the amount of manure produced has increased correspondingly and has caused environmental problems in various parts of the world. This is due, in part, to the accumulation of phosphate from manure in surface waters which has caused eutrophication. For other background information, see European Patent Application Publication No. 420 358.

Phytases (myo-inositol hexakisphosphate phosphohydrolases; EC 3.1.3.8) are enzymes that hydrolyze phytate (myo-inositol hexakisphosphate) to myo-inositol and inorganic phosphate and are known to be valuable feed additives.

A phytase was first described in rice bran in 1907 [Suzuki et al., Bull. Coll. Agr. Tokyo Imp. Univ. 7, 495 (1907)] and phytases from Aspergillus species in 1911 [Dox and Golden, J. Biol. Chem. 10, 183-186 (1911)]. Phytases have also been found in wheat bran, plant seeds, animal intestines and in microorganisms [Howsen and Davis, Enzyme Microb. Technol. 5, 377-382 (1983), Lambrechts et al., Biotech. Lett. 14, 61-66 (1992), Shieh and Ware, Appl. Microbiol. 16, 1348-1351 (1968)].

The cloning and expression of the phytase from Aspergillus niger (ficuum) has been described by Van Hartingsveldt et al., in Gene, 127, 87-94 (1993) and in European Patent Application, Publication No. 420 358 and from Aspergillus niger var awamori by Piddington et al. in Gene 133, 55-62 (1993).

Since phytases used so far in agriculture have certain disadvantages, it is an object of the present invention to provide new phytases or polypeptides having phytase activity with improved properties. Since it is known that phytases used so far lose activity during feed pelleting process due to heat treatment, improved heat tolerance would be such an improved property.

So far, phytases have not been reported in thermotolerant fungus with the exception of Aspergillus fumigatus [Dox and Golden et al., J. Biol. Chem. 10, 183-186 (1911)] and Rhizopus oryzae [Howson and Davies, Enzyme Microb. Technol. 5, 377-382 (1993)]. Thermotolerant phytases have been described originating from Aspergillus terreus Strain 9A-1 [Temperature optimum 70° C.; Yamada et al., Agr. Biol. Chem. 32, 1275-1282 (1968)] and Schwanniomyces castellii [Temperature optimum 77° C.; Segueilha et al., Bioeng. 74, 7-11 (1992)]. However for commercial use in agriculture such phytases must be available in large quantities. Accordingly it is an object of the present invention to provide DNA sequences coding for heat tolerant phytases. Improved heat tolerance of phytases encoded by such DNA sequences can be determined by assays known in the art, for example, by the processes used for feed pelleting or assays determining the heat dependence of the enzymatic activity itself as described, for example, by Yamada et al. (s.a.).

It is furthermore an object of the present invention to screen fungi which show a certain degree of thermotolerance for phytase production. Such screening can be made as described, for example, in Example 1. In this way heat tolerant fungal strains, listed in Example 1, have been identified for the first time to produce a phytase.

Heat tolerant fungal strains, see for example, those listed in Example 1, can then be grown as known in the art, for example, as indicated by their supplier, for example, the American Tissue Type Culture Collection (ATCC), Deutsche Sammlung von Mikroorganismen und Zellkulturen GmbH (DSM), Agricultural Research Service Culture Collection (NRRL) and the Centralbureau voor Schimmelcultures (CBS) from which such strains are available or as indicated, for example, in Example 2.

Further improved properties are, for example, an improved substrate specificity regarding phytic acid [myo-inositol(1,2,3,4,5,6)hexakisphosphate] which is a major storage form of phosphorous in plants and seeds. Since for the complete release of the six phosphate groups from phytic acid, a phytase and a pH 2.5. acid phosphatase activity are required, a polypeptide having phytase and pH 2.5 acid phosphatase activity would be highly desirable. For example, International Patent Application Publication No. 94/03072 discloses an expression system which allows the expression of a mixture of phytate degrading enzymes in desired ratios. However, it would be even more desirable to have both such activities in a single polypeptide. Therefore it is also an object of the present invention to provide DNA sequences coding for such polypeptides. Phytase and phosphatase activities can be determined by assays known in the state of the art or described, for example, in Example 9.

Another improved property is, for example, a so called improved pH-profile. This means, for example, two phytin degrading activity maxima, for example, one at around pH 2.5 which could be the pH in the stomach of certain animals and another at around pH 5.5 which could be the pH after the stomach in certain animals. Such pH profile can be determined by assays known in the state of the art or described, for example, in Example 9. Accordingly it is also an object of the present invention to provide DNA sequences coding for such improved polypeptides.

It is yet another object of the present invention to provide a DNA sequence coding for a polypeptide having phytase activity and which DNA sequence is derived from a fungus selected from the group consisting of Acrophialophora levis, Aspergillus terreus, Aspergillus fumigatus, Aspergillus nidulans, Aspergillus sojae, Calcarisporiella thermophila, Chaetomium rectopilium, Corynascus thermophilus , Humicola sp., Mycelia sterilia, Myrococcum thermophilum, Myceliophthora thermophila, Rhizomucor miehei, Sporotrichum cellulophilum, Sporotrichum thermophile, Scytalidium indonesicum and Talaromyces thermophilus or a DNA sequence coding for a fragment of such a polypeptide which fragment still has phytase activity, or more specifically such a DNA sequence wherein the fungus is selected from the group consisting of Acrophialophora levis, Aspergillus fumigatus, Aspergillus nidulans, Aspergillus terreus, Calcarisporiella thermophila, Chaetomium rectopilium, Corynascus thermophilus, Sporotrichum cellulophilum, Sporotrichum thermophile, Mycelia sterilia, Myceliophthora thermophila and Talaromyces thermophilus , or more specifically such a DNA sequence wherein the fungus is selected from the group consisting of Aspergillus terreus, Myceliophthora thermophila, Aspergillus fumigatus, Aspergillus nidulans and Talaromyces thermophilus .

“Fragments” and “standard conditions ” have the meaning as given above. “Degenerate variant ” means in this context a DNA sequence which because of the degeneracy of the genetic code has a different nucleotide sequence as the one referred to but codes for a polypeptide with the same amino acid sequence. “Equivalent” refers in this context to a DNA sequence which codes for polypeptides having phytase activity with an amino acid sequence which differs by deletion, substitution and/or addition of one or more amino acids, preferably up to 50, more preferably up to 20, even more preferably up to 10 or most preferably 5, 4, 3 or 2, from the amino acid sequence of the polypeptide encoded by the DNA sequence to which the equivalent sequence refers to. Amino acid substitutions which do not generally alter the specific activity are known in the state of the art and are described, for example, by H. Neurath and R. L. Hill in “The Proteins” (Academic Press, New York, 1979, see especially FIG. 6 , page 14).

Furthermore it is an object of the present invention to provide a DNA sequence as specified above wherein the encoded polypeptide is a phytase.

Furthermore, it is an object of the present invention to provide the polypeptides encoded by the above described DNA sequences which have phytase activity and fragments of the polypeptides which retain phytase activity, and in particular those polypeptides of SEQ ID NO:2, SEQ ID NO:4, SEQ ID NO:6, SEQ ID NO:8, SEQ ID NO:10, SEQ ID NO:12, SEQ ID NO:29, SEQ ID NO:11, SEQ ID NO:33, and SEQ ID NO:35.

Genomic DNA or cDNA from fungal strains can be prepared as known in the art [see for example, Yelton et al., Procd. Natl. Acad. Sci. USA, 1470-1474 (1984) or Sambrook et al., s.a., or other standard reference for preparing CDNA from fungi] or, for example, as specifically described in Example 2.

The cloning of the DNA-sequences of the present invention from such genomic DNA can then be effected, for example, by using the well known polymerase chain reaction (PCR) method. The principles of this method are outlined for example, by White et al. (1989), whereas improved methods are described for example, in Innis et al. [PCR Protocols: A guide to Methods and Applications, Academic Press, Inc. (1990)]. PCR is an in vitro method for producing large amounts of a specific DNA of defined length and sequence from a mixture of different DNA-sequences. Thereby, PCR is based on the enzymatic amplification of the specific DNA fragment of interest which is flanked by two oligonucleotide primers which are specific for this sequence and which hybridize to the opposite strands of the target sequence. The primers are oriented with their 3′ ends pointing toward each other. Repeated cycles of heat denaturation of the template, annealing of the primers to their complementary sequences and extension of the annealed primers with a DNA polymerase result in the amplification of the segment between the PCR primers. Since the extension product of each primer can serve as a template for the other, each cycle essentially doubles the amount of the DNA fragment produced in the previous cycle. By utilizing the thermostable Taq DNA polymerase, isolated from the thermophilic bacteria Thermus aquaticus, it has been possible to avoid denaturation of the polymerase which necessitated the addition of enzyme after each heat denaturation step. This development has led to the automation of PCR by a variety of simple temperature-cycling devices. In addition, the specificity of the amplification reaction is increased by allowing the use of higher temperatures for primer annealing and extension. The increased specificity improves the overall yield of amplified products by minimizing the competition by non-target fragments for enzyme and primers. In this way the specific sequence of interest is highly amplified and can be easily separated from the non-specific sequences by methods known in-the art, for example, by separation on an agarose gel and cloned by methods known in the art using vectors as described for example, by Holten and Graham in Nucleic Acid Res. 19, 1156 (1991), Kovalic et. al. in Nucleic Acid Res. 19, 4560 (1991), Marchuk et al. in Nucleic Acid Res. 19, 1154 (1991) or Mead et al. in Bio/Technology 9, 657-663 (1991).

The oligonucleotide primers used in the PCR procedure can be prepared as known in the art and described for example, in Sambrook et al. (1989 “Molecular cloning” 2nd edt., Cold Spring Harbor Laboratory Press, Cold Spring Harbor).

The specific primers used in the practice of the present invention have been designed as degenerate primers on the basis of DNA-sequence comparisons of known sequences of the Aspergillus niger phytase, the Aspergillus niger acid phosphatase, the Saccharomyces cerevisiae acid phosphatase and the Schizosaccharomyces pombe acid phosphatase (for sequence information see, for example, European Bioinformatics Institute (Hinxton Hall, Cambridge, GB). The degeneracy of the primers was reduced by selecting some codons according to a codon usage table of Aspergillus niger prepared on the basis of known sequences from Aspergillus niger . Furthermore it has been found that the amino acid at the C-terminal end of the amino acid sequences used to define the specific probes should be a conserved amino acid in all acid phosphatases including phytases specified above but the rest of the amino acids should be more phytase than phosphatase specific.

Such amplified DNA-sequences can than be used to screen DNA libraries of DNA of, for example, fungal origin by methods known in the art (Sambrook et al., s.a.) or as specifically described in Examples 5-7.

Once complete DNA-sequences of the present invention have been obtained they can be integrated into vectors by methods known in the art and described for example, in Sambrook et al. (s.a.) to overexpress the encoded polypeptide in appropriate host systems. However, one skilled in the art knows that also the DNA-sequences themselves can be used to transform the suitable host systems of the invention to get overexpression of the encoded polypeptide. Appropriate host systems are for example fungi, like Aspergilli, for example, Aspergillus niger ATCC 91421 or Aspergillus ficuum [NRRL 31351 or like Trichoderma, for example, Trichoderma reesei or yeasts, like Saccharomyces, for example, Saccharomyces cerevisiae or Pichia, like Pichia pastoris , all available from ATCC. Bacteria which can be used are for example, E. coli , Bacilli as, for example, Bacillus subtilis or Streptomyces, for example, Streptomyces lividans (see for example, Anné and Mallaert in FEMS Microbiol. Letters 114, 121 (1993). E. coli , which could be used are E. coli K12 strains for example, M15 [described as DZ 291 by Villarejo et al. in J. Bacteriol. 120, 466-474 (1974)], HB 101 [ATCC No. 33694] or E. coli SG13009 (Gottesman et al., J. Bacteriol. 148, 265-273 (1981)].

Vectors which can be used for expression in fungi are known in the art and described for example, in EP 420 358, or by Cullen et al. [Bio/Technology 5, 369-376 (1987)] or Ward in Molecular Industrial Mycology, Systems and Applications for Filamentous Fungi, Marcel Dekker, New York (1991), Upshall et al. [Bio/Technology 5, 1301-1304 (1987)] Gwynne et al. [Bio/Technology 5, 71-79 (1987)], Punt et al. [J. of Biotechnology 17, 19-34 (1991)] and for yeast by Sreekrishna et al. [J.

Suitable vectors which can be used for expression in E. coli are mentioned, for example, by Sambrook et al. [s.a.] or by Fiers et al. in Procd. 8 th Int. Biotechnology Symposium” [Soc. Franc. de Microbiol., Paris (Durand et al., eds.), pp. 680-697 (1988)] or by Bujard et al. in Methods in Enzymology, eds. Wu and Grossmann, Academic Press, Inc. Vol. 155, 416-433 (1987) and Stüber et al. in Immunological Methods, eds. Lefkovits and Pernis, Academic Press, Inc., Vol. IV, 121-152 (1990). Vectors which could be used for expression in Bacilli are known in the art and described, for example, in EP 405 370, Procd. Nat. Acad. Sci. USA, 81, 439 (1984) by Yansura and Henner, Meth. Enzym. 185, 199-228 (1990) or EP 207 459.

Either such vectors already carry regulatory elements, for example, promotors or the DNA-sequences of the present invention can be engineered to contain such elements. Suitable promotor-elements which can be used are known in the art and are, for example, for Trichoderma reesei the cbh1- [Haarki et al., Biotechnology 7, 596-600 (1989)] or the pki1-promotor [Schindler et al., Gene 130, 271-275 (1993)], for Aspergillus oryzae the amy-promotor [Christensen et al., Abstr. 19 th Lunteren Lectures on Molecular Genetics F23 (1987), Christensen et al., Biotechnology 6, 1419-1422 (1988), Tada et al., Mol.

Genet. 22, 21-27 (1992)]. Suitable promotor-elements which could be used for expression in yeast are known in the art and are, for example, the pho5-promotor [Vogel et al., Molecular and Cellular Biology, 2050-2057 (1989); Rudolf and Hinnen, Proc. Natl. Acad. Sci. 84, 1340-1344 (1987)] or the gap-promotor for expression in Saccharamyces cerevisiae und for Pichia pastoris , for example, the aox1-promotor [Koutz et al. Yeast 5, 167-177 (1989); Sreekrishna et al., J. Basic Microbiol. 28, 265-278 (1988)].

Accordingly vectors comprising DNA sequences of the present invention, preferably for the expression of said DNA sequences in bacteria or a fungal or a yeast host and such transformed bacteria or fungal or yeast hosts are also an object of the present invention.

Once such DNA-sequences have been expressed in an appropriate host cell in a suitable medium the encoded phytase can be isolated either from the medium in the case the phytase is secreted into the medium or from the host organism in case such phytase is present intracellularly by methods known in the art of protein purification or described, for example, in EP 420 358. Accordingly a process for the preparation of a polypeptide of the present invention characterized in that transformed bacteria or a host cell as described above is cultured under suitable culture conditions and the polypeptide is recovered therefrom and a polypeptide when produced by such a process or a polypeptide encoded by a DNA sequence of the present invention are also an object of the present invention.

Example 1

Screening Fungi for Phytase Activity

Fungi were screened on a three plate system, using the following three media: “M3” a defined medium containing phosphate); “M3-P” (M3 medium lacking phosphate); and “M3 P+Phytate” (M3 medium lacking phosphate but containing phytate as a sole phosphorus source). Plates were made with agarose to decrease the background level of phosphate.

Fungi were grown on the medium and at the temperature recommended by the supplier. Either spores or mycelium were transferred to the test plates and incubated at the recommended temperature until growth was observed.

The following thermotolerant strains were found to exhibit growth consistent with the production of an extracellular phytase:

Myceliophthora thermophila [ATCC 48102]

Talaromyces thermophilus [ATCC 20186]

Aspergillus fumigatus [ATCC 346251]

Example 2

Growth of Fungi and Dreparation of Genomic DNA

Strains of Myceliophthora thermophila, Talaromyces thermophilus, Aspergillus fumigatus, Aspergillus nidulans and Aspergillus terreus 9A-1 were grown in Potato Dextrose Broth (Difco Lab., Detroit, Mich., USA) or complete medium (Clutterbuck). Aspergillus terreus 9A-1 and Aspergillus nidulans have been deposited under the Budapest Treaty for patent purposes at the DSM in Braunschweig, BRD at Mar. 17, 1994 under accession number DSM 9076 and at Feb. 17, 1995 under accession number DSM 9743, respectively.

Genomic DNA was Prepared as Follows:

Medium was innoculated at a high density with spores and grown overnight (O/N) with shaking. This produced a thick culture of small fungal pellets. The mycelium was recovered by filtration blotted dry and weighed. Up to 2.0 g was used per preparation. The mycelium was ground to a fine powder in liquid nitrogen and immediately added to 10 mls of extraction buffer (200 mM Tris/HCl, 250 mM NaCl, 25 mM EDTA, 0.5% SDS, pH 8.5) and mixed well. Phenol (7 mls) was added to the slurry and mixed and then chloroform (3 mls) was also added and mixed well. The mixture was centrifuged (20,000 g) and the aqueous phase recovered. RNase A was added to a final concentration of 250 μ/ml and incubated at 37° C. for 15 minutes. The mixture was then extracted with 1 volume of chloroform and centrifuged (10,000 g, 10 minutes). The aqueous phase was recovered and the DNA precipitated with 0.54 volumes of RT isopropanol for 1 hour at room temperature (RT). The DNA was recovered by spooling and resuspended in water.

The Resultant DNA was Further Purified as Follows:

A portion of the DNA was digested with proteinase K for 2 hrs at 37 °C. and then extracted repeatedly (twice to three times) with an equal volume of phenol/chloroform and then ethanol precipitated prior to resuspension in water to a concentration of approximately 1 μg/μl.

Example 3

Degenerate PCR

PCR was performed essentially according to the protocol of Perkin Elmer Cetus [(PEC); Norwalk, Conn., USA]. The following two primers were used (bases indicated in brackets are either/or):

Phyt 8: 5′ ATG GA(C/T) ATG TG(C/T) TC(N) TT(C/T) GA 3′ [SEQ ID NO:15]

Degeneracy =32

Tm High =60° C./Tm Low 52° C.

Phyt 9: 5′ TT(A/G) CC(A/G) GC(A/G) CC(G/A) TG(N) CC(G/A) TA 3′

[SEQ ID NO:16]

Tm High =70° C./Tm Low 58° C.

A typical Reaction was Performed as Follows:

	H 2 O	24.5	μl
	10× PEC GeneAmp Buffer	5	μl
	GeneAmp dNTP's (10 mM)	8	μl
	Primer 1 (Phyt 8, 100 μM)	5	μl
	Primer 2 (Phyt 9, 100 μM)	5	μl
	DNA (˜1 μg/μl)	1	μl
	Taq Polymerase (PEC)	0.5	μl
		50	μl

All components with the exception of the Taq polymerase were incubated at 95 ° C. for 10 minutes and then 50° C. for 10 minutes and then the reaction placed on ice. The Taq polymerase (Amplitaq, F. Hoffmann-La Roche, Basel, CH) was then added and 35 cycles of PCR performed in a Triothermoblock (Biometra, Göttingen, DE) according to the following cycle profile:

95° C./60″

50° C./90″

72° C./120″

An aliquot of the reaction was analyzed on 1.5% agarose gel.

Example 4

Subcloning and Sequencing of PCR Fragments

PCR products of the expected size (approximately 146 bp predicted from the Aspergillus niger DNA-sequence) were excised from low melting point agarose and purified from a NACS—PREPAC—column (BRL Life Technologies Inc., Gaithersburg, Md., USA) essentially according to the manufacturer's protocol. The fragment was polyadenylated in 50 μl 100 mM Sodiumcacodylate pH6.6, 12.5 mM Tris/HCI pH 7.0, 0.1 mM Dithiothreitol, 125 μg/ml bovine serum albumin, 1 mM CoCl 2 , 20 μMdATP, 10 units terminal deoxytransferase (Boehringer Mannheim, Mannheim, DE) for 5 minutes at 37° C. and cloned into the p123T vector [Mitchell et al., PCR Meth. App. 2, 81-82 (1992)].

Alternatively, PCR fragments were purified and cloned using the “Sure Clone” ligation kit (Pharmacia) following the manufacturers instructions.

Sequencing was performed on dsDNA purified on a Quiagen-column (Diagen GmbH, Hilden, DE) using the dideoxy method and the Pharmacia T7 kit (Pharmacia, LKB Biotechnology AB, Uppsala, SE) according to the protocol supplied by the manufacturer.

Example 5

Construction and Screening of Lambda Fix II Libraries

The fragments from Aspergillus terreus Strain 9A-1 and Myceliophthora thermophila were used to probe BamHI and BglII southerns to determine the suitable restriction enzyme to use to construct genomic libraries in the Lambda Fix II vector (Strategene, La Jolla, Calif., USA). Lambda Fix II can only accept inserts from 9-23 kb. Southerns were performed according to the following protocol. Genomic DNA (10 gg) was digested in a final volume of 200 μl. The reaction without enzyme was prepared and incubated on ice for 2 hours. The enzyme (50 units) was added and the reaction incubated at the appropriate temperature for 3 hours. The reaction was then extracted with an equal volume of phenol/chloroform and ethanol precipitated. The resuspended DNA in loading buffer was heated to 65° C. for 15 minutes prior to separation on a 0.7% agarose gel (O/N 30 V). Prior to transfer the gel was washed twice in 0.2 M HCl/10′/room temperature (RT) and then twice in 1 M NaCl/0.4 M NaOH for 15′ at RT. The DNA was transferred in 0.4 M NaOH in a capillary transfer for 4 hours to Nytran 13 N nylon membrane (Schleicher and Schuell AG, Feldbach, Zürich, CH). Following transfer the membrane was exposed to UV. [Auto cross-link, UV Stratalinker 2400, Stratagene (La Jolla, Calif., USA)].

The membrane was prehybridized in hybridization buffer [50% formamide, 1% sodium dodecylsulfate (SDS), 10% dextransulfate, 4×SSPE (180 mM NaCl, 10 mM NaH 2 PO 4 , 1 mM EDTA, ph 7.4)] for 4 hours at 42° C. and following addition of the denatured probe O/N at 42° C. The blot was washed:

1×SSPE/0.5% SDS/RT/30 minutes

0.1×SSPE/0.1% SDS/RT/30 minutes

0.1×SSPE/0.1% SDS/65° C./30 minutes

Results indicate that Aspergillus terreus Strain 9A-1 genomic DNA digested with BamHI and Myceliophthora thermophila genomic DNA digested with BglII produce fragments suitable for cloning into the lambda Fix II vector.

The construction of genomic libraries of Aspergillus terreus Strain 9A-1 and Myceliophthora thermophila in Lambda Fix II was performed according to the manufacturer's protocols (Stratagene).

The lambda libraries were plated out on 10 137 mm plates for each library. The plaques were lifted to Nytran 13N round filters and treated for 1 minute in 0.5 M NaOH/1.5 M NaCl followed by 5 minutes in 0.5 M Tris-HCl pH 8.0/1.5 M NaCl. The filters were then treated in 2×SSC for 5 minutes and air dried. They were then fixed with UV (1 minute, UV Stratalinker 2400, Stratagene). The filters were hybridized and washed as above. Putative positive plaques were cored and the phage soaked out in SM buffer (180 mM NaCl, 8 MM MgSO 4 .7H 2 O, 20mM Tris/HCl pH 7.5, 0.01% gelatin). This stock was diluted and plated out on 137 mm plates. Duplicate filters were lifted and treated as above. A clear single positive plaque from each plate was picked and diluted in SM buffer. Three positive plaques were picked. Two from Aspergillus terreus Strain 9A-1 (9A1λ17 and 9A1λ22) and one from Myceliophthora thezmophila (MTλ27).

Example 6

Preparation of Lambda DNA and Confirmation of the Clones

Lambda DNA was prepared from the positive plaques. This was done using the “Magic Lambda Prep” system (Promega Corp., Madison, Wis., USA) and was according to the manufactures specifications. To confirm the identity of the clones, the lambda DNA was digested with PstI and SalI and the resultant blot probed with the PCR products. In all cases this confirmed the clones as containing sequences complementary to the probe.

Example 7

Subcloning and Sequencing of Phytase Genes

DNA from 9A1λ17 was digested with PstI and the resultant mixture of fragments ligated into pBluescript II SK+ (Stratagene) cut with PstI and treated with shrimp alkaline phosphatase (United States Biochemical Corp., Cleveland, Ohio, USA). The ligation was O/N at 16° C. The ligation mixture was transformed into XL-1 Blue Supercompetent cells (Stratagene) and plated on LB Plates containing 0.5 mM isopropyl-β-D-thiogalactopyranoside (IPTG), 40 μg/ml 5-bromo-4-chloro-3-indoyl-β-D-galactopyranoside (Xgal), 50 μg/ml ampicillin.

DNA from 9Aλ17 was digested with BglII and XbaI and the resultant mixture ligated into pBluescript II SK+ digested with BamHI/XbaI. Ligation, transformation and screening were performed as described above.

DNA from MTλ27 was digested with SalI and the resultant mixture of fragments ligated into pBluescript II SK+ cut with SalI and treated with shrimp alkaline phosphatase. The ligation was O/N at 16° C. The ligation mixture was transformed into XL1 Blue Supercompetent cells and plated on LB Plates containing Xgal/IPTG and ampicillin.

Colonies from the above transformations were picked and “gridded” approximately 75 to a single plate. Following O/N incubation at 37° C. the colonies were lifted to a nylon filter (“Hybond-N”, Amersham Corp., Arlington Heights, Ill., USA) and the filters treated with 0.5 M NaOH for 3 minutes, 1 M Tris/HCl pH7.5 twice for 1 minute, then 0.5 M Tris/HCl pH7.5/1.5 M NaCl for 5 minutes. The filters were air dried and then fixed with UV (2 minutes, UV Stratalinker 2400, Stratagene). The filters were hybridized with the PCR products of Example 5. Positive colonies were selected and DNA prepared. The subclones were sequenced as previously described in Example 4. Sequences determined are shown in FIG. 1 ( FIG. 1 ) for the phytase from Aspergillus terreus strain 9A1 and its encoding DNA sequence, FIG. 2 for the phytase from Myceliophthora thermophila and its encoding DNA-sequence, FIG. 3A shows a restriction map for the DNA of Aspergillus terreus (wherein the arrow indicates the coding region, and the strips the regions sequenced in addition to the coding region) and 3B for M. thermophila , and FIG. 4 for the phytase from Talaromyces thermophilus and its encoding DNA sequence, FIG. 5 for the phytase from Aspergillus fumigatus and its encoding DNA-sequence and FIG. 6 for the phytase from Aspergillus nidulans and its encoding DNA-sequence. The sequences for the phytases and its encoding DNA-sequences from Talaromyces thermophilus, Aspergillus fumigatus and Aspergillus nidulans were obtained in the same way as described for those of Aspergillus terreus strain 9A1 and Myceliophthora thermophila in Examples 2-7. Bases are given for both strands in small letters by the typically used one letter code abbreviations. Derived amino acid sequences of the phytase are given in capital letters by the typically used one letter code below the corresponding DNA-sequence.

Example 8

Construction of a Chimeric Construct Between A. niger and A. terreus Phytase DNA-sequences

All constructions were made using standard molecular biological procedures as described by Sambrook et al., (1989) (Molecular Cloning, A Laboratory Manual, Cold Spring Harbor Laboratory Press, NY).

The first 146 amino acids (aa) of the Aspergillus niger phytase, as described in EP 420 358, were fused to the 320 Cterminal aa of the Aspergillus terreus 9A1 gene. A NcoI site was introduced at the ATG start codon when the A. niger phytase gene was cloned by PCR. The intron found in the A. niger phytase was removed by site directed mutagenesis (Bio-Rad kit, Cat Nr 170-3581; Bio-Rad, Richmond, Calif., USA) using the following primer (wherein the vertical dash indicates that the sequence to its left hybridizes to the 3′ end of the first exon and the sequence to its right hybridizes to the 5′ end of the second exon):

5′-AGTCCGGAGGTGACT|CCAGCTAGGAGATAC-3′ [SEQ ID NO:19].

To construct the chimeric construct of phytases from A. niger and A. terreus an Eco 47III site was introduced into the A. niger coding sequence to aid cloning. PCR with a mutagenic primer (5′ CGA TTC GTA gCG CTG GTA G 3′) in conjunction with the T3 primer was used to produce a DNA fragment that was cleaved with BamHI and Eco 47III. The BamHI/Eco 47III fragment was inserted into BamHI/Eco 47III cut p9A1Pst (Example 7). FIG. 7 shows the amino acid sequence of the fusion construct and its encoding DNA-sequence.

Example 9

Expression of Phytases

Construction of Expression Vectors

For expression of the fusion construct in A. niger an expression cassette was chosen where the fusion gene was under control of the inducible A. niger glucoamylase (glaA) promoter.

For the complete A. terreus 9A1 gene, expression cassettes with the constitutive A. nidulans glyceraldehyde-3-phosphate dehydrogenase (gpdA) promoter were made.

All genes used for expression in A. niger carried their own signal sequence for secretion.

Construction of Vector pFPAN1

The A. niger glucoamylase (glaA) promoter was isolated as a 1960 bp XhoI/ClaI fragment from plasmid pDH33 [Smith et al. (1990), Gene 88: 259-262] and cloned into pBluescriptSK + -vector (pBS) [Stratagene, La Jolla, Calif., USA] containing the 710 bp BamHI/XbaI fragment of the A. nidulans trpC terminator. The plasmid with the cassette was named pGLAC. The fusion gene, as described in Example 8, was put under control of the A. niger glaA promoter by ligating the blunt ended NcoI/EcoRI fragment to the blunt ended ClaI site and the EcoRV site of plasmid pGLAC. The correct orientation was verified by restriction enzyme digests. The entire cassette was transferred as a KpnI/XbaI fragment to pUC19 (New England Biolabs, GmbH, Schwalbach, BRD), that carried the Neurospora crassa pyr4 gene (pUC19-pyr4), a selection marker in uridine auxotrophic Aspergilli, resulting in vector pFPAN1 (see FIG. 8 with restriction sites and coding regions as indicated; crossed out restriction sites indicate sites with blunt end ligation).

Construction of Vector pPAT1

The A. nidulans glyceraldehyd-3-phosphate dehydrogenase (gpdA) promoter was isolated as a ˜2.3 kb EcoRI/NcoI fragment from plasmid pAN52-1 [Punt et al. (1987), Gene 56: 117-124], cloned into pUC19-NcoI (pUC19 having a SmaI-site replaced by a NcoI-site), reisolated as EcoRI/BamHI fragment and cloned into pBS with the trpC terminator as described above. The obtained cassette was named pGPDN. The A. terreus gene was isolated as a NcoI/EcoRI fragment, where the EcoRI site was filled in to create blunt ends. Plasmid pGPDN was cut with BamHI and NcoI. The BamHI site was filled in to create blunt ends. The NcoI/EcoRI(blunt) fragment of the A. terreus gene was cloned between the gpda promoter and trpC terminator. The expression cassette was isolated as KpnI/XbaI fragment and cloned into pUC19-pyr4 resulting in plasmid pPAT1 (see FIG. 9 ; for explanation of abbreviations see legend to FIG. 8 ).

Single transformants were isolated, purified and tested for overproduction of the fusion protein. 100 ml M25 medium (70 g maltodextrin (Glucidex 17 D, Sugro Basel, CH), 12.5 g yeast extract, 25 g casein-hydrolysate, 2 g KH 2 PO 4 , 2 g K 2 SO 4 , 0.5 g MgSO 4 .7H 2 O, 0.03 g ZnCl 2 , 0.02g CaCl 2 , 0.05 g MnSO 4 .4H 2 O, 0.05 g FeSO 4 per liter pH 5.6) were inoculated with 10 6 spores per ml from transformants FPAN1#11, #13, #16, #E25, #E30 respectively #E31 and incubated for 5 days at 30° C. and 270 rpm. Supernatant was collected and the activity determined. The fusion protein showed the highest activity with phytic acid as substrate at pH 2.5, whereas with 4-nitrophenyl phosphate as substrate it showed two activity optima at pH 2.5 and 5.0 (Table 1).

C) Activity Assay

a) Phytic Acid

A 1 ml enzyme reaction contained 0.5 ml dialyzed supernatant (diluted if necessary) and 5.4 mM phytic acid (SIGMA P-3168). The enzyme reactions were made in 0.2 M sodium acetate buffer pH 5.0, respectively 0.2 M glycine buffer pH 2.5. The samples were incubated for 15 min at 37° C. The reactions were stopped by adding 1 ml 15% TCA (trichloroacetic acid).

For the colour reaction 0.1 ml of the stopped sample was diluted with 0.9 ml distilled water and mixed with 1 ml reagent solution (3 volumes 1 M H 2 SO 4 , 1 volume 2.5% (NH 4 ) 6 Mo 7 O 24 , 1 volume 10% ascorbic acid). The samples were incubated fot 20 min at 50° C. and the blue color was measured spetrophotometrically at 820 nm. Since the assay is based on the release of phosphate a phosphate standard curve, 11-45 nmol per ml, was used to determine the activity of the samples.

b) 4-Nitrophenyl Phosphate

A 1 ml enzyme reaction contained 100 μl dialyzed supernatant (diluted if necessary) and 1.7 mM 4-nitrophenyl phosphate (Merck, 6850, Darmstadt, BRD). The enzyme reactions were made in 0.2 M sodium acetate buffer pH 5.0, respectively 0.2 M glycine buffer pH 2.5. The samples were incubated for 15 min at 37° C. The reactions were stopped by adding 1 ml 15% TCA.

For the determination of the enzyme activity the protocol described above was used.

DNA sequences in bold show the sense primer and in italics the antisense primer. The primers correspond to the indicated part of the coding sequence of the Aspergillus niger gene. The combinations used are primers 8 plus 9 and 10 plus 11. The Taq-Start antibody kit from Clontech (Palo Alto, Calif., USA) was used according to the manufacturer's protocol. Primer concentrations for 8 plus 9 were 0.2 mM and for primers 10 plus 11 one mM. Touch-down PCR was-used for amplification [Don, R. H. et al. (1991), Nucleic Acids Res. 19, 4008]. First the DNA was denatured for 3 min at 95° C. Then two cycles were done at each of the following annealing temperatures: 60° C., 59° C., 58° C., 57° C., 56° C., 55° C., 54° C., 53° C., 52° C. and 51° C., with an annealing time of one min. each. Prior to annealing the incubation was heated to 95° C. for one min and after annealing elongation was performed for 30 sec at 72° C. Cycles 21 to 35 were performed as follows: denaturation one min at 95° C., annealing one min at 50° C. and elongation for 30 sec at 72° C.

Two different PCR fragments were obtained. The DNA sequences obtained and their comparison to relevant parts of the phytase gene of Aspergillus terreus 9A1 are shown in FIG. 10 [relevant parts of the phytase gene of Aspergillus terreus 9A1 “9A1 ”(top lines) (1) and the PCR fragments of Aspergillus terreus CBS 116.46 “aterr2” (bottom lines). Panel A: Fragment obtained with primer pair 8 plus. 9 (aterr21). Panel B: Fragment obtained with primer pair 10 plus 11 (aterr58). DNA sequences of Aspergillus terreus CBS 116.46 (top lines) are compared with those of Aspergillus terreus 9A1 (1) (bottom lines). PCR amplifications were performed as described in the legend to Table 4. Panel A: The bold gc sequence (bases 16 plus 17) in the aterr21 fragment could possibly be cg (DNA sequencing uncertainty). Panel B: The N at position 26 of the aterr58 PCR fragment could possibly represent any of the four nucleotides].

Cross Hybridizations under Non-stringent and Stringent Washing Conditions

Five mg's of genomic DNA of each strain listed in Table 3 were incubated with 4 units of HindIII or PstI, respectively, per mg of DNA at 37° C. for 4 hours. After digestion, the mixtures were extracted with phenol and DNAs were precipitated with ethanol. Samples were then analyzed on 0.8% agarose gels. DNA-s were transferred to Nytran membranes (Schleicher & Schuell, Keene, N.H., USA) using 0.4M NaOH containing 1M NaCl as transfer solution. Hybridizations were performed for 18 hours at 42° C. The hybridization solution contained 50% formamide, 1% SDS, 10% dextran sulphate, 4×SSPE (1×SSPE=0.18M NaCl, 1 mM EDTA, 10 mM NaH2 PO 4 , pH 7.4), 0.5% blotto (dried milk powder in H 2 O) and 0.5 mg salmon sperm DNA per ml. The membranes were washed under non-stringent conditions using as last and most-stringent washing condition incubation for 30 min at room temperature in 0.1×SSPE containing 0.1% SDS. The probes (labeled at a specific activity of around 10 9 dpm/mg DNA) used were the PCR fragments generated with primers 8 plus 9 (see Example 11) using genomic DNA of Myceliophthora thermophila; Mycelio. thermo.; Aspergillus nidulans, Asperg. nidul.; Aspergillus fumigatus, Asperg. fumig.,; Aspergillus terreus 9A1 , Asperg. torrous 9A1 . Talaromyces thermophilus, Talarom. thermo . The MT2 genomic probe was obtained by random priming (according to the protocol given by Pharmacia, Uppsala, Sweden) and spans 1410 bp, from the BspEI site upstream of the N-terminus of the Mycelo. thezmo . phytase gen to the PvuII site in the C-terminus (positions 2068 is to 3478). The AT2 genomic probe was obtained by random priming and spans 1365 bp, from the ApaI site to the NdeI site of the Auperg. terreus 9A1 phytase gene (positions 491 to 1856). The AN2 DNA probe was obtained by random priming and spans the complete coding sequence (1404 bp) of the Asperg. niger gene (EP 420 358). Results are given in Table 3. [“*” except for weak signal corresponding to a non-specific 20 kb fragment; In case of the very weak cross-hybridization signal at 20 kb seen with DNA from Aspergillus niger using the PCR fragment from Talaromyces thermophilus this signal is unspecific, since it differs significantly from the expected 10 kb HindIII-fragment, containing the phytase gene; “**” signal due to only particle digest of DNA].

For cross-hybridizations with stringent washing conditions membranes were further washed for 30 min. at 65° C. in 0.1×SSPE containing 0.1% SDS. Results are shown in Table 4 [ (1) only the 10.5-kb HindIII fragment is still detected, the.6.5-kb HindIII fragment disappeared (see Table 3)].

The complete phytase encoding genes of Aspergllus nidulans, Talaromyces thermophilus, Aspergillus fumigatus , and Aspergillus terreus (CBS116.46) are provided for in a manner set forth below.

Organisms and growth conditions: Aspergillus nidulans (DSM 9743), Aspergillus fumigatus (ATCC 34625), Aspergillus terreus (CBS 116.46) and Talaromyces thermophilus (ATCC 20186) were grown on potato dextrose broth (Difco Lab., Detroit, Mich., USA) at 28° C. except for T. thermophilus , a thermotolerant fungus, which was grown at 45° C. Transformed E. coli (TG-1) were grown in Luria broth (LB) at 37° C. with 100 μg/ml ampicillin for selection.

Gencmic DNA: Fungal mycelium was obtained by incubating potato dextrose medium at a high density with spores O/N (200 rpm) at the temperatures indicated above. Up to 2 grams of the mycelium, obtained by filtration through a Whatmann filter, were used for the isolation of genomic DNA as described in the present application.

DNA amplification: Genomic DNA of the coding regions of the different phytase genes was amplified using PCR on a Gene Amp Kit (Perkin Elmer Cetus) according to the manufacturer's instructions using degenerate primers:

Primer 8: 5′ -ATGGA(C/T)ATGTG(C/T)TC(N)TT(C/T)GA-3′ [SEQ ID NO:15]

Primer 9: 5′-TT(A/G)CC(A/G)GC (A/G)CC(G/A)TG(N)CC(A/G)TA-3′ [SEQ ID NO:16]

Primer 10: 5′-TA(C/T)GC(N)GA(C/T)TT(C/T)TC(N)CA(C/T) GA-3′ [SEQ ID NO:17]

Primer 11: 5′-CG(G/A)TC(G/A)TT(N)AC(N)AG(N)AC(N)C-3′ [SEQ ID NO:18]

For T. thermophilus all components of the reaction, including the primers 8 [SEQ ID NO:15] and 9 [SEQ ID NO:16] at a final concentration of 10 mM, but with the exception of the Taq polymerase, were incubated at 95° C. for 10 min and 50° C. for 1 min before the reaction was placed on ice. The Taq polymerase was then added and 35 cycles of PCR performed according to the following cycle profiles: 60 sec, 95° C./60 sec, 50° C./90 sec, 72° C./120 sec.

For A. nidulans, A. terreus CBS116.46 and A. fumigatus a “touch-down” PCR with a final primer concentration of 0.2 mM for primers 8 [SEQ ID NO:151 and 9 [SEQ ID NO:16] was performed as described in Don, R. H., Cox, P. T., Wainwright, B. J., Baker, K., Mattick, J. S., “Touchdown” PCR to circumvent spurious priming during gene amplification. Nucleic Acids Res., 19:4008 (1991).]. In the case of A. terreus CBS116.46 additional amplifications with primers 10 [SEQ ID NO:17] and 11 [SEQ ID NO:18] at a final concentration of 1 mM were also done. In all “touch-down” reactions first the DNA was denatured for 3 min at 95° C., followed by two cycles at each of the following annealing temperatures: 60° C., 59° C., 58° C., 57° C., 56° C., 55° C., 54° C., 53° C., 52 and 51° C., with an annealing time of one min each. Prior to annealing the incubation was heated to 95° C. for one min and after annealing elongation was performed for 30 sec at 72° C. Cycles 21 to 35 were performed as follows: denaturation one min at 95° C., annealing one min at 50° C. and elongation for 30 sec at 72° C. As template, 1 μg of the genomic DNA was used in a total reaction mixture of 50 μl.

Primers Aterr21, Aterr58, Terr380 and Terr1810 were used to isolate the complete A. terreus CBS 116.46 phytase gene by PCR (see results). The A. terreus CBS 116.46 specific primer, Aterr21 (5′-CTGTCGCCGTTCTGCGACC TC-3′) [SEQ ID NO:20] and Aterr 58 (5′CGGTGCCGTTGTACAGACCCAGC-3′) [SEQ ID NO:21] were designed using the nucleotide sequence of the two PCR fragments obtained with primers 8 [SEQ ID NO:15] and 9 [SEQ ID NO:16] and primers 10 [SEQ ID NO:17] and 11 [SEQ ID NO:18] on genomic DNA of A. terreus CBS116.46 (see FIG. 11 ). Primer Terr380 (5′ATGGGCTTTCTTGCCATTGT-3′) [SEQ ID NO:22] and Terrl8 lO (5′TCAGAAACAATCCGCCCAAGTT-3′) [SEQ ID NO:23] are specific for the 5′ and 3′ of the coding sequence of the phytase gene of A. terreus 9A1.

In all cases an aliquot of the reaction was analysed on 1.5% agarose gel. PCR products of the expected size were excised from the agarose and isolated by centrifugation of the gel slices through siliconized glass wool as described by Heery, D. M., Gannon, F. and Powell, R., A simple method for subcloning DNA fragments from gel slices. Trends. Genet., 6:173 (1990) or using a GENECLEAN Kit (BIO101.Inc.) essentially according to the manufacturer's protocol. The fragment was subsequently cloned 25 into pUC 18 using the Sure-Clone ligation kit (Pharmacia).

Southern blot analysis: Southern hybridization experiments were performed to construct genomic maps to find appropriate DNA fragments carrying the phytase gene. Genomic DNA (3 μg) was digested with the different restriction enzymes as indicated in the legends of the figures and electrophoresed on a 0.75% agarose gel. The transfer to Zeta-Probe blotting membranes (BIO-RAD) was done as described in Southern, E. M., Detection of specific sequences among DNA fraaments separated by gel electrophoresis. J. Mol. Biol., 98:503 (1975). Prehybridization and hybridization was in 7% SDS, 1% BSA (fraction V; Boehringer), 0.5M Na 2 HPO 4 , pH 7.2 at 65° C. Probes derived from PCR products of the respective phytase genes (see FIG. 11 ) were labeled with (α- 32 P)-dGTP (Amersham) by random-priming according to Sambrook, J., Fritsch, E. F., Maniatis, T., Molecular Cloning: a laboratory manual. Second Edition ed. 1989, Cold Spring Harbor N.Y., Cold Spring Harbor Laboratory Press, U.S.A. and used in the hybridization experiments. After hybridization the membranes were washed twice for 5 minutes in 2×SSC., 1% SDS at room temperature and twice for 15 minutes in 0.1% SSC., 0.1% SDS at 65° C. before exposure O/N on Kodak X-Omat AR film.

Library construction: Prior to the partial library construction, Southern blot analysis with a given probe was done in order to identify a specific restriction fragment of interest. Subsequently 10-20 μg of genomic DNA was digested with the appropriate restriction enzymes and electrophoresed on an agarose gel. According to comigrating DNA markers, the region of interest was cut out of the gel, the DNA isolated and subcloned into the pBluescriptII—(KS) vector. Transformation of the ligation mixture into E. coli TG-1 cells resulted in partial genomic libraries carrying the fragment of interest. The genomic A. fumigatus (NIH stock#5233) Lambda FIXII library was obtained from Stratagene (cat. Nr. 946055). The size of the cloned fragments, generated by partial Sau3AI digestion of genomic DNA were in the range of 9-22 kb, according to the manufacturer.

Screening of genomic libraries: E. coli transformants of the partial genomic libraries of A. nidulans, A. terreus CBS 116.46 and T. thermophilus were screened using the colony lift assay described in Sambrook, J., Fritsch, E. F., Maniatis, T., Molecular Cloning: a laboratory manual. Second Edition ed. 1989, Cold Spring Harbor N.Y., Cold Spring Harbor Laboratory Press, U.S.A. and the appropriate probe (see FIG. 11 ). The A. fumigatus Lambda FIXII library was screened according to the manufacturer's instructions using the DNA fragment PCRAfu as probe. Putative positive plaques were cored and subjected to a second round of purification. A clear single positive plaque was picked and used to make a large scale phage preparation as described in Sambrook, J., Fritsch, E. F., Maniatis, T., Molecular Cloning: a laboratory manual. Second Edition ed. 1989, Cold Spring Harbor N.Y., Cold Spring Harbor Laboratory Press, U.S.A. The analysis of the DNA insert and further subcloning steps are outlined herein.

DNA sequencing: The sequence was determined by the dideoxy chain termination technique described in Sanger, F., Nicklen, S. and Coulson, A. R., DNA sequencing with chain-terminating inhibitors. Proc. Natl. Acad. Sci. USA., 74:5463-5467 (1977) using the Sequenase Kit (United States Biochemical). Both strands were completely sequenced and the sequence analyzed using the GCG sequence analysis software package (Version 8.0) by Genetics Computer, Inc. See Devereux, J., Haeberli, P. and Smithies, O., A comprehensive set of sequence analysis programs for the VAX. Nucleic Acids Res., 12:387-395 (1984).

Cloning fragments of phytase genes by PCR: To have suitable probes for the library screening, specific DNA fragments of the different phytases were obtained by performing PCR on. genomic DNA of the individual fungi using degenerate primers as described above. These degenerate PCR amplifications on genomic DNA with primers 8 [SEQ ID NO:15] and 9 [SEQ ID NO:16] gave discrete bands of about 120 to 130 bp for A. nidulans, A. fumigatus, T. thermophilus and about 150 bp for A. terreus CBS 116.46. Furthermore amplification with primers 10 [SEQ ID NO:17] and 11 [SEQ ID NO:18] on genomic DNA of A. terreus CBS116.46 gave a amplification product of 220 bp. The sequences of these fragments are shown in FIG. 11 .

The A. nidulans phytase: To identify and isolate DNA fragments carrying the putative phytase gene the PCR fragment PCRAni ( FIG. 11 ) was used to probe a Southern blot carrying chromosomal DNA of A. nidulans digested with different restriction enzymes (FIG. 12 ). The 6 kb HindIII/KpnI fragment hybridizing to the probe seemed the most suitable for cloning Genomic A. nidulans DNA was digested with HindIII and KpnI and electrophoresed on an agarose gel. According to comigrating DNA markers, the region of about 5-7 kb was cut out of the gel and the DNA isolated. One positive transformant, clone 1, was chosen and the sequence determined. FIG. 13 shows 1931 nts of the insert [SEQ ID NO:28] carrying the complete phytase gene. The encoded protein [SEQ ID NO:29] consists of 463 amino acids with a theoretical MW of 51785 Da and is interrupted by a single intron with a predicted length of 54 nts and positioned close to the 5′ of the gene. In the open reading frame (ORF) upstream of the intron there is one additional potential initiation codon at position 125-127 followed by a putative signal peptide, however when the amino acid sequences of all known phytases are aligned the ATG at position 158 -160 is the most likely translation start site.

The T. themchiwus phytase: A partial library with BamHI/XbaI fragments of about 4.7 kb was constructed based on the Southern blot analysis results with genomic DNA of T. thermophilus (FIG. 14 ). One positive transformant, clone Tt29, was chosen and sequencing reactions with primer and reverse primer performed. Sequencing data showed that the BamHI restriction site was present within the phytase gene and therefore only part of the complete gene had been isolated. Comparison of the amino acid sequence to known phytase proteins predicted that we had cloned the C-terminus of the putative phytase gene. To get the missing N-terminus a chromosome walking approach was taken using 5′ end of clone Tt29 (a 370 bp BamHI-BstEII fragment) as probe, to hybridize to T. thermophilus genomic DNA double digested with BstEII and a number of other restriction enzymes (FIG. 15 ). The 4.5 kb EcoRI/BstEII DNA fragment identified by the probe was the most appropriate for cloning. Genomic DNA digested with EcoRI and BstEII and having a size between 4 and 5 kb was isolated and subcloned into the EcoRI and BstEII sites of plasmid Tt29-1. Plasmid Tt29-1 is a shorter variant of construct Tt29, and was obtained by deleting a 3.6 kb. SacI fragment. This reduction of the plasmid size was done to avoid instability problems which potentially could arise when cloning the 4.5 kb EcoRI-BstEII fragment into the plasmid Tt29, already containing a 4.7 kb DNA insert. Transformant carrying the Tt29-132 construct were identified by hybridization to the BamHI-BstEII DNA probe. One positive clone carrying the EcoRI-SacI insert of approx. 5.5 kb was chosen and the phytase sequence determined. FIG. 16 shows a linear map of the position of the insert of the plasmid clones Tt29, Tt29-1 and Tt29-132.

The 1845 nts of the insert Tt29-132 [SEQ ID NO:30] are shown in FIG. 17 . The phytase gene of T. thermophilus encodes, interrupted by a single intron located similar to the above mentioned phytase genes, a protein [SEQ ID NO:31] of 466 amino acids. The theoretical molecular weight is 51450 Da.

One additional potential initiation codon is present upstream at position 236-238 followed by a putative signal sequence. However based on amino acid homology comparisons to the other phytases the ATG at position 288-290 is the most likely translation initiation site.

The A. fumigatus phytase: Screening of 5.3×10 6 plaques of the A. fumigatus FIXII library with the probe PCRAfu gave 115 hybridizing plaques. Two plaques were picked and subjected to a second round of purification. Bacteriophage DNA of the two candidates was isolated and digested with NotI. The Lambda clone having the largest insert (approx. 15 kb) was further mapped by restriction analysis and genomic Southern. FIG. 18 shows the position of the BamHI fragment within the insert of the bacteriophage lambda clone. The 6 kb BamHI fragment giving a strong signal with the above mentioned probe was isolated, subcloned and part of the sequence encoding the phytase gene was determined. FIG. 19 shows 1571 nts of the insert [SEQ ID NO:32] carrying the complete phytase gene. One single intron of 56 nts is found close to the 5′ of the gene. This is in accordance with the aforementioned phytase genes. The enzyme. consists of 465 amino acids [SEQ ID NO:33] with a theoretical MW of 50704 Da.

The A. terres CBS 116.46 phytase: Based on the high sequence identity seen between both strains of A. terreus , 9A1 and CBS 116.46, we tried to isolate the phytase gene of the latter strain by PCR, using primers derived from the 5′ and 3′ of the A. terreus 9A1 sequence (Terr 380 [SEQ ID NO:22] and Terr 1810 [SEQ ID NO:23] ) and two internal primers (Aterr 21 [SEQ ID NO:20] and Aterr 58 [SEQ ID NO:21]) derived from the A. terreus CBS 116.46 DNA fragments described in FIG. 11 . FIG. 20 outlines the position of the primers on the phytase gene of A. terreus strain 9A1 and the expected amplification products. Only primer Atterr 21 [SEQ ID NO:20] and Terr 1810 [SEQ ID NO:23] gave a product with an expected size of about 570 bp. The PCR fragment was cloned into the SmaI site of pUC18, resulting in plasmid pUC18-569. Sequencing of the insert confirmed that we had cloned the C-terminus of the phytase gene. The missing N-terminus of the gene was cloned basically as described for the other phytases. Southern blot analysis of genomic DNA of A. terreus CBS-116.46, with the 570 bp A. terreus CBS116.46 DNA piece as probe, identified a KpnI/KpnI fragment of 2 kb carrying the complete phytase gene. The region of about 2 kb was isolated and used to construct a partial genomic library. One E. coli transformant, clone 227, hybridizing to the probe was then used for further analysis. FIG. 21 shows 1567 nts of the insert [SEQ ID NO:34]. The encoded phytase has 466 amino acids [SEQ ID NO:35] and a theoretical molecular weight of 51054 Da.

The phytases from Aspergillus fumigatus, A. nidulans, A. terreus 9A1 , A. terreus CBS, and Myceliophthora thermophila were overexpressed in A. niger or Hansenula polymozpha and purified to apparent homogeneity. After removal of the cells, the clear culture supernatant was concentrated by ultrafiltration and subjected to buffer exchange on a Fast Desalting Column HR 10/10 (Pharmacia). Final purification was achieved by cation exchange chromatography on either a Mono S HR 5/5 (Pharmacia) or a Poros HS/M column (PerSeptive Biosystems) in the case of A. fumigatus phytase (FIG. 22 ). The sample was loaded in a buffer containing 10 mM sodium acetate, pH 5.0 . A. fumigatus phytase was eluted ith a linear gradient from 10 mM sodium acetate, pH 5.0 to 10 mM sodium acetate, 1 M NaCl, pH 5.0. Anion exchange chromatography on a Poros HQ/M column (PerSeptive Biosystems) was used in the case of the other phytases.

In order to corroborate the identities of the purified proteins, samples were separated by SDS-PAGE and blotted onto PVDF membranes (Immobilon-P SQ , Millipore). N-terminal sequencing of the proteins was done by automated Edman degradation on an Applied Biosystems 494A sequencer with on-line microbore phenylthiohydantoin detection. The results of the N-terminal sequencing are set forth in Table 5.

For the determination of the specific activity of the respective proteins, protein concentration was calculated from OD 280 according to the theoretical absorption calculated from the amino acid sequences. Phytase activity was measured in an assay mixture containing 0.5% phytic acid (˜5 mM), 200 mM sodium acetate, pH 5.0. After a 15 min-incubation period at 37° C., the reaction was stopped by addition of an equal volume of 15% TCA. The liberated phosphate ions were quantified by mixing 100 μl of the assay mixture with 900 μl H 2 O and 1 ml of 0.6 M H 2 SO 4 , 2% ascorbic acid and 0.5% ammonium molybdate. Standard solutions of potassium phosphate were used as reference. One unit (U) is defined as the amount of protein liberating 1 μmol of inorganic phosphate per minute at 37° C.
