Description

FIELD OF THE INVENTION

The present invention relates to an almond N-glycosidase gene and genes associated therewith, which are useful in sugar chain technology such as analyses of structures and functions of sugar chains and glycoproteins. The present invention also relates to vectors in which such genes are integrated, recombinant microorganisms transformed with said vectors, and a process for preparing the almond N-glycosidase using the recombinant microorganisms.

BACKGROUND OF THE INVENTION

Almond N-glycosidase (EC 3.5.1.52) was found by Takahashi et al. at the first time as an enzyme which hydrolyses a .beta.-aspartyl glycosylamin bond of an asparagine-linked type (N-linked type) sugar chain of a glycopeptide �Takahashi et al., Biochemical and Biophysical Research Communications, 76: 1194-1201 (1977)!. This enzyme liberates only asparagine-linked type sugar chains with their roots from various glycoproteins (glycopeptides) existing in biological tissues, cell membranes and so on. In addition, this enzyme has a broad substrate specificity for structures of sugar chains, so that it can liberate any of high mannose type, mixed type and complex type sugar chains. Because of these properties, this enzyme is widely used and very effective in cutting sugar chains out of glycoproteins (glycopeptides) to determine structures of sugar chains, analyses of changes of bioactivities of glycoproteins by removing sugar chains therefrom, or identification of existence of sugar chains in glycoproteins (glycopeptides) and determination of molecular weights of the protein portions from changes of molecular weights thereof by the action of this enzyme.

Firstly, an almond N-glycosidase was partially purified by Takahashi et al., and existence of three types of almond N-glycosidases each of which had different substrate specificity were reported �Biochimica et Biophysica Acta), 657: 457-467 (1981)!. Then, this enzyme was partially purified by Tarentino, and existence of three types of almond N-glycosidases were reported like the report of Takahashi et al. �Journal of Biological Chemistry, 257: 10776-10780 (1982)!. However, unlike the report of Takahashi et al., it was reported that no difference in the substrate specificity was found in these three types of almond N-glycosidases.

In addition, Taga et al. isolated an almond N-glycosidase as a single peptide at the first time �Biochemistry, 23: 815-822 (1984)!. Taga et al. reported that almond glycosidase was a single chain polypeptide, the molecular weight of which was 66,800 on sodium lauryl sulfate-polyacryl-amide gel electrophoresis (SDS-PAGE), and that this protein was a glycoprotein having sugar chains. Also, Taga et al. reported that this enzyme contained proteins which had different charges, and that .beta.-hexosaminidase contaminating in this enzyme could not be removed. Kaliberda, E. Net al. showed that an almond glycosidase was a single chain protein, the molecular weight of which was 71,000 on SDS-PAGE, and that the amino acid sequence of the amino terminal was Ile-Asp-Pro-Arg-Val-Val-Xaa-Ala-Xaa-Leu- (SEQ ID NO: 3) �Bioorganicheskaya Khimiya, 16: 751-758 (1990)!.

As described above, it has been reported that almond N-glycosidase is a glycoprotein, and also reported that several types of the enzyme which have different isoelectric points exist, and that the isolated protein is single chain protein.

An almond N-glycosidase purified from an acetone powder extract of almond seeds is commercially available. However, generally, the acetone powder extract of almond seeds contains many kinds of and a large amount of sugar degrading enzymes, so that it is difficult to isolate only an almond N-glycosidase. Consequently, utilization of the enzyme purified from almond seeds is always accompanied with a risk of contamination of the other sugar degrading enzymes. Especially, it is very difficult to obtain a highly purified N-glycosidase protein from viewpoint of the enzyme activity, which can be used in microscale analyses. Moreover, an almond N-glycosidase itself is a glycoprotein having N-linked sugar chains, therefore the utilization of the almond N-glycosidase is accompanied with a risk of contamination of sugar chains from itself.

On the other hand, the structure and the amino acid sequence of this enzyme are unknown. In addition, a process of preparing almond N-glycosidase which has industrial advantages has not been disclosed yet. If the gene of this enzyme is elucidated, it will be possible to produce a highly purified and homogeneous enzyme preparation by genetic engineering, and also possible to produce enzymes without sugar chains which are useful in sugar chain engineering such as analyses of structures and functions of sugar chains and glycoproteins. Also, by the DNA sequence of this enzyme, it will be possible to search genes analogous to the DNA sequence of this enzyme, which are expected to possess similar activities to this enzyme, while the sequences are different from that of this enzyme. Moreover, the amino acid sequence corresponding to this enzyme is useful in preparing an antibody against this enzyme.

DETAILED DESCRIPTION OF THE INVENTION

To obtain the almond N-glycosidase of the present invention, firstly, the almond N-glycosidase in an acetone powder was subjected to various chromatographies to be highly purified.

It was found that the purified almond N-glycosidase protein was composed of a light chain and a heavy chain, the molecular weights of which were 27000 and 60000 on SDS-PAGE, respectively, which are not covalently bonded each other. It has not been shown heretofore in the prior art that an almond N-glycosidase is composed of such two polypeptides. In addition, it has been quite unknown whether they are coded on different genes and expressed individually, or coded on the same gene and generated by a cleavage after translation into proteins.

Therefore, for cloning of a cDNA coding the almond N-glycosidase, unlike the case where an usual single chain polypeptide is cloned, it is necessary to consider the relationship between genes for the two polypeptides as above mentioned. For cloning the cDNA coding the almond N-glycosidase, for example, the following procedure can be used.

Firstly, the amino acid sequences of the portions of the highly purified two polypeptides of the almond N-glycosidase, that is, the light chain and the heavy chain are analyzed. The amino acid sequences of these portions can be determined from N-terminal of the proteins directly by Edman method. Alternatively, the sequences can be determined by hydrolysing the proteins into fragments with a protease such as trypsin and lysyl endopeptidase, isolating and purifying them, then determining individually. On the basis of the amino acid sequences of these portions, synthesized DNAs of appropriate length are prepared according to the fluctuation to be used as primers or probes. Then, RNA is extracted from a tissue abundant in the almond N-glycosidase, for example almond seeds, and poly(A)-RNA is purified therefrom using a carrier such as a latex carrier to which oligo-(dT) is bound. cDNA is synthesized using the poly(A)-RNA as a template by the action of reverse transcriptase. The DNA is inserted into a plasmid or a phage vector, and introduced into a host to make a cDNA library according to a method, for example Okayama-Berg method or Gubler-Hoffmann method.

As for procedures to obtain a cDNA coding the desired almond N-glycosidase, for example the following two procedures can be applied.

One procedure is to screen the cDNA library directly using the DNA previously synthesized as a probe. Alternatively, it is effective to use the DNA fragment as a probe when the portion of the desired cDNA has been obtained. That is, firstly, the library is cultured on plates, and colonies or plaques grown are transferred to nitrocellulose membranes or nylon membranes, then the DNAs are immobilized to the membranes by denaturation. These membranes are incubated in a solution containing the probe DNA labelled with for example .sup.32 P to form hybrids (hereinafter referred this treatment as hybridization). The incubation temperature is set slightly lower than the Tm (melting temperature) of the probe used. After hybridization, non-specifically adsorbed matters are washed out, and clones hybridized to the probe are identified by a means such as autoradiography. In addition, in this case, when hybridization to the library DNA immobilized to a membrane is carried out using the DNAs corresponding to the partial amino acid sequences of the light chain and the heavy chain, respectively as probes, the relationship between the light chain and the heavy chain will be clarified by whether hybridization to the same clone occurs or not. This operation is repeated until the hybridized clones become a single clone. The cDNA coding the desired protein is inserted into the clone thus obtained.

Another procedure is to amplify the cDNA coding the desired almond N-glycosidase using the cDNA as a template synthesized from the poly(A)-RNA from almond seeds by PCR (polymerase-chain-reaction) method. As the primers which are used, a pair of synthesized DNAs assumed from the partial amino acid sequence of the almond N-glycosidase; the synthesized DNA and a random primer (a mixture of the all sequences); or the synthesized DNA and a primer the sequence of which is known, are exemplified. To use the primers the sequence of which are known, it is necessary to add a region to the terminal of the desired DNA, to which the primers having known sequences can anneal. To add the region, a known method in which DNA ligase is used can be used. The amplification is not always occur by any probe, especially non-specific amplification or no amplification tends to occur because synthesized DNA assumed from the partial amino acid sequence contains mixed sequences, therefore it is necessary to investigate what primers that have been prepared according to what partial amino acid sequence should be used, and what combination of the primers should be used. In addition, it is necessary to select the PCR condition suitable to the primers.

To amplify the desired DNA effectively, it is effective to carry out nested PCR. That is, firstly, PCR is performed among primers which have been prepared, then using the amplified product as a template, the second PCR is performed using primers coding the inner sequences compared with the primers used in the primary PCR. For PCR method, a gene amplifying kit containing Taq polymerase, and an automatic gene amplifying apparatus are available from Takara Shuzo Co., Ltd. The desired DNA region can be amplified using them.

Further, DNA primers are synthesized on the basis of the sequences of the cDNA fragments of the light chain and the heavy chain amplified by PCR. Depending on whether amplification can occur using primers from the heavy chain and the light chain or not, it is clarified whether the light chain and the heavy chain are coded on the same gene or not, in other words, the relationship of the location of the light chain and the heavy chain on the gene is clarified.

The sequence of the cDNA obtained is determined, and identified whether it is the desired gene or not. In case that the clone has been obtained by hybridization, it is cultured, for example in a test tube to extract the plasmid according to a conventional method when the recombinant is E. coli. This plasmid is digested by a restriction enzyme to obtain a fragment for insertion. The fragment is subcloned into a vector such as M13 phage vector to determine the sequence by dideoxy method.

When the recombinant is a phage, sequencing can be carried out basically in similar steps. In case that the cDNA has been obtained by PCR method, the amplified DNA is purified by agarose gel electrophoresis, and the terminal is blunt-ended. The DNA is subcloned into a vector such as M13 phage, and the sequence is determined by dideoxy method. As for these experimental methodologies from culture to nucleotide sequencing, see for example T. Maniatis et al., Molecular Cloning. A Laboratory Manual (1982), Cold Spring Harbor Laboratory.

The molecular weight, and the result obtained by the N-terminal analysis of the almond N-glycosidase, the gene structure and the amino acid sequence can be determined by comparing the determined sequence with the partial amino acid sequence. When the cDNA which has been obtained does not contain the coding region of the almond N-glycosidase at all, the whole nucleotide sequence of the coding region can be determined by synthesizing DNA primers on the basis of the nucleotide sequence obtained to amplify the lacking portion by PCR, or by further screening the cDNA library using the fragment of the cDNA obtained as a probe.

To obtain a polypeptide or a protein which has an almond N-glycosidase activity, firstly, the almond N-glycosidase gene is connected with a vector that can express them in a suitable host cell, for example bacteria such as E coli, Bacillus subtilis, yeasts, animal cells, insect cells, and plant cells, then the transformation is performed thereby to prepare a recombinant organism. By culturing the recombinant organism, the polypeptide having the almond N-glycosidase can be produced.

Construction of such a vector, and transformation of the host cell using them are preformed by methods known to those skilled in the art. Alternatively, a polypeptide without sugar chain can be expressed by using cells as hosts which do not have an ability of synthesizing sugar chains, for example, procaryotes such as E. coli and Bacillus subtilis, or mutant cells of yeasts, animal calls, insect cells and plant cells, which have lost an ability of synthesizing sugar chains.

The polypeptide or the protein can be accumulated as an insoluble matter (inclusion body), depending on the expression system used. In this case, the activity can be recovered by collecting the insoluble matter, and solubilize it under a mild condition, for example with urea, then removing the denaturating reagent.

The expression can be confirmed by assaying the almond N-glycosidase activity. For example, the assay can be carried out using dabsyl ovomucoid glycopeptide (manufactured by Genzyme) as a substrate according to the manual appended. That is, after incubation the enzyme solution with dabsyl ovomucoid at 37.degree. C., assay of the almond glycosidase activity can be performed by separating and detecting the dabsyl peptide produced by liberation of the sugar chain from the substrate, using reverse phase chromatography and thin layer chromatography.

Alternatively, after labelling the reducing terminal of the sugar chain which has been liberated by pyridylamination, the activity can be assayed by separation and quantification of the labelled sugar chain using high performance liquid chromatography.

To purify a polypeptide or a protein which has an almond glycosidase activity from the transformant, common chromatography techniques can be used. For example, when the cultured cells have been broken and the desired polypeptide has been solubilized, the desired polypeptide expressed can be obtained by subjecting the supernatant of the culture to chromatographies such as hydrophobic, ion exchange and gel filtration. When the expressed product is accumulated as an insoluble matter, the cells are broken, and the precipitation is collected to be solubilized with a denaturating reagent such as urea. Then, the polypeptide or the protein having the desired activity can be obtained after removing the denaturating reagent and refolding.

An example of determination of the structure of the almond N-glycosidase gene is shown below.

Firstly, cDNA for the N-terminal of the heavy chain is amplified by PCR method to determine the nucleotide sequence.

The N-terminal amino acid sequence of the highly purified heavy chain of the almond N-glycosidase protein is determined. The sequence is shown in SEQ ID NO: 4. A sense mixed primer HNT1 (SEQ ID NO: 5) corresponding to the portion of amino acids 3-9, and a sense mixed primer HNT2 (SEQ ID NO: 6) corresponding to the portion of amino acids 8-14 are synthesized by a DNA synthesizer, and purified. Inner partial amino acid sequences are shown in SEQ ID NO: 7 to 14. Anti sense mixed primers are synthesized on the basis of these sequences, and purified.

That is, an anti sense mixed primer HIC1 (SEQ ID NO: 15) corresponding to the region of amino acids 12-19 of the inner sequence of the heavy chain shown in SEQ ID NO: 7, and an anti sense mixed primer HIC2 (SEQ ID NO: 16) and HIC3 (SEQ ID NO: 17) corresponding to the region of amino acids 12-19 and 2-8, respectively, shown in SEQ ID NO: 11 are synthesized.

The first chain of the cDNA is prepared using d(T).sub.20 M4 (SEQ ID NO: 18) as a primer synthesized by a DNA synthesizer using the mRNA from almond seeds as a template. Using the primers and the first chain of the cDNA, nested PCR is carried out.

The primary PCR is carried out using the first chain of the cDNA as a template, and using three combinations of primers, HNT1 and HIC1, HNT1 and HIC2, and HNT1 and HIC3. Each reaction mixture is named PCR1, PCR2 and PCR3. The secondary PCR is carried out using three reaction mixtures from the primary PCR as templates respectively, and using three combinations of primers to each template, that is, HNT2 and HIC1, HNT2 and HIC2, and HNT2 and HIC3. Each reaction mixture is named PCR-1, PCR1-2, PCR1-3, PCR2-1, PCR2-2, PCR2-3, PCR3-1, PCR3-2 and PCR3-3. A fragment about 500 bp which is specifically amplified N-terminal portion of the heavy chain (FHN) is obtained only from PCR2-2 of the reaction mixtures from the secondary PCR. This FHN is cloned. For the four clones, inserted sequences of the FHN (FHN1-FHN4) are determined. These sequences are shown in SEQ ID NO: 19-22, respectively.

Then, cDNA containing the C-terminal portion of the heavy chain is amplified by PCR method to determine the nucleotide sequence. For this determination, two primers shown in SEQ ID NO: 23 and 24 are designed from the sequences of FHN1-FHN4 which have been already determined, and synthesized by a DNA synthesizer. That is, these two primers are sense primer HI1 and HI2 shown in SEQ ID NO: 23 and SEQ ID NO: 24, which correspond to nucleotides 72-95 and nucleotides 148-164 of FHN1-FHN4, respectively, shown in SEQ ID NO 19-22. Further, a synthesized DNA M13 primer M4 (SEQ ID NO: 25, Takara Shuzo Co., Ltd.) which has the same sequence as nucleotides 1-17 of d(T)20M.sub.4 (SEQ ID NO: 18) is used as an anti sense primer. Using these primers and the first chain of the cDNA, nested PCR is carried out.

The primary PCR is carried out using the first chain of the cDNA as a template, and HI1 (SEQ ID NO: 23) and M13 primer M4 (SEQ ID NO: 25) as primers. The secondary PCR is carried out using the reaction mixtures from the primary PCR as templates, and HI2 (SEQ ID NO: 24) and M13 primer M4 (SEQ ID NO: 25) as primers. By the secondary PCR, a DNA fragment of approximately 1.2 Kbp (FHC) containing the C-terminal portion of the heavy chain which has been amplified specifically. This FHC is cloned. For the four clones, inserted sequences of the FHC (FHC1-FHC4) are determined. The sequences are shown in SEQ ID NO: 26-29.

Then, cDNA containing the full length of the light chain of the almond N-glycosidase is amplified by PCR to determine the nucleotide sequence.

As in the case of the heavy chain, the N-terminal amino acid sequence of the highly purified light chain of the almond N-glycosidase protein is determined. The sequence is shown in SEQ ID NO: 30.

On the basis of the amino acid sequence of the light chain (SEQ ID NO: 30), sense mixed primers shown in SEQ ID NO: 31-34 are designed respectively, and synthesized by a DNA synthesizer, then purified. Also, on the basis of the sequence of the cDNA of the heavy chain previously determined, 10 anti sense mixed primers are designed, and synthesized by a DNA synthesizer, then purified.

That is, sense mixed primers LN1C and LN1T shown in SEQ ID NO: 31 and SEQ ID NO: 32 which correspond to amino acids 1-8 of the N-terminal sequence of the light chain shown in SEQ ID NO: 30; a sense mixed primer LN2 shown in SEQ ID NO: 33 which corresponds amino acids 6-12 thereof; and a primer LN3 shown in SEQ ID NO: 34 which corresponds to amino acids 12-18 thereof are synthesized. In addition, as an anti sense primer, primer HIC4 shown in SEQ ID NO: 35 which corresponds to nucleotides 262-286 of SEQ ID NO: 19-22 and to nucleotides 125-149 of SEQ ID NO: 32-35 is synthesized. Using these primers and the first chain of the cDNA, nested PCR is carried out. When the light chain and the heavy chain exist tandem in this order on the same gene, it is possible that the gene coding the full length of the light chain and the N-terminal portion of the heavy chain is amplified.

The primary PCR is carried out using the first chain of the cDNA as a template, and using three combinations of primers, LN1C and HIC4, LN1T and HIC4, and LN2 and HIC4. Each reaction mixture is named PCR4, PCR5 and PCR6. The secondary PCR is carried out using three reaction mixtures from the primary PCR as templates respectively. To templates PCR4 and PCR5, the secondary PCR is carried out using two combinations 10 of primers, that is, LN2 and HIC4, and LN3 and HIC4. The reaction mixtures are named PCR4-1, PCR4-2, PCR5-1 and PCR5-2, respectively. To a template PCR6, the PCR reaction is carried out using primers LN3 and HIC4, and the reaction mixture named PCR6-1. An amplified DNA fragment of approximately 900 bp containing N-termini of the light chain and the heavy chain (FL) is obtained only from reaction mixtures PCR4-1 and PCR5-2. Therefore, it is thought that the light chain and the heavy chain are coded tandem in this order on the same gene.

Then, FL is cloned. For the six clones, the nucleotide sequences of the FL (FL1-FL6) inserted are determined. The sequences are shown in SEQ ID NO: 36-41, respectively. When no DNA fragment containing the light chain is amplified by the method above mentioned, the relation of the location between the light chain and the heavy chain can be investigated after determination using the similar procedure in the case of the heavy chain.

The relationship among FHN, FHC and FL above described, and the individual restriction maps are shown in FIG. 1. The region coding the almond N-glycosidase is determined by applying the result of the analysis of the amino acid sequence of the almond N-glycosidase to the sequences of FHN, FHC and FL. The nucleotide sequence of the cDNA which can code the almond N-glycosidase is shown in SEQ ID NO: 2, and the amino acid sequence which can be coded by the nucleotide sequence can code is shown SEQ ID NO: 1.

To produce a polypeptide or a protein having an almond N-glycosidase activity, firstly, the DNA coding the almond N-glycosidase is connected with a vector. In this case, either a fragment FL or FHC amplified by PCR, or a synthesized DNA can be used as a DNA coding the almond N-glycosidase. Alternatively, the nucleotide sequence can be selected so that it will fit for the sequence determined by the analysis of the partial amino acid sequence of the almond N-glycosidase. The polypeptide having the almond N-glycosidase activity can be produced by introducing the vector for expression of the almond N-glycosidase thus obtained into a host cell, and culturing the transformed cell. As a host cell, the cell above mentioned can be used. For example, a fission yeast such as Schizosaccharomyces pombe ATCC 38440 can be used. In the examples below, Schizosaccharomyces pombe strain T-1 which is belong to the present applicants and have the same characters as 38400 is used.

Using these genes obtained as probes, all N-glycosidase genes which have slightly different sequences and are expected to have the similar activity can be obtained by hybridization under a stringent condition. As sources of the gene to be hybridized, DNAs and mRNAs obtained from bacteria, fungi, plant and animal cells can be used. For example, as for plants, DNAs and mRNAs obtained from tissues such as seeds and shoots can be used, and as for animals, DNAs and mRNAs obtained from cultured cells and tissues of internal organs can be used.

Examples of plants contain plants of Family Rosaceae such as apricot, plum, peach, cherry and loquat, and plants of different families, for example plants of Family leguminosae such as sword bean, horse bean, liquorice, wisteria, pea, clara, and plants of Family Brassicaceae and Family cucurbitaceae, and Family Solanaceae.

Such a stringent condition is, for example, as follows: DNA which is immobilized to a nylon membrane is hybridized to a probe in a solution containing 6.times.SSC (1.times.SSC consists of sodium chloride 8.7 g, and sodium citrate 4.41 g in 1 L of water), 1% sodium lauryl sulfate, 100 .mu.g/ml salmon sperm DNA, and 5.times.Denhart's (containing 0.1% bovine serum albumin, 0.1% polyvinylpyrrolidone and 0.1% Ficoll), at 65.degree. C. for 20 hours.

To obtain the desired gene coding the N-glycosidase by hybridization, for example, following method can be applied: firstly, chromosomal DNA obtained from the desired gene source, or cDNA prepared from mRNA by reverse transcriptase is connected to a plasmid or a phage vector according to a conventional method to prepare a library. The library is cultured on plates. Grown colonies or plaques are transferred 10 onto a nitrocellulose or a nylon membrane, and the DNAs are immobilized to the membrane by denaturation. This membrane is incubated in a solution containing a probe previously labelled with for example .sup.32 P to hybridize the DNA on the membrane to the probe. A Probe used include a gene coding an amino acid sequence described SEQ ID NO: 1 or a portion thereof. For example, a gene described in SEQ ID NO: 2 or a portion thereof can be used. For example, a gene coding an amino acid sequence described in SEQ ID NO: 4, 7, 8, 9, 10, 11, 12, 13, 14, 19, 20, 21, 22, 26, 27, 28, 29, 30, 36, 37, 38, 39, 40 or 41, or a portion thereof can be used. For example, hybridization between DNA immobilized to a membrane and a probe is carried out in a solution containing 6.times.SSC, 1% sodium lauryl sulfate, 100 .mu.g/ml salmon sperm DNA, and 5.times.Denhart's (containing bovine serum albumin, polyvinylpyrrolidone, Ficoll, each 0.1%) at 65.degree. C. for 20 hours. After hybridization, non-specifically adsorbed matters are washed out, and hybridized clones are identified by a means such as autoradiography. This operation is repeated until the hybridized clones become a single clone. The gene coding the desired protein is inserted in the clone thus obtained.

The gene obtained is sequenced, for example as described below and identified to code the desired N-glycosidase.

To determine the nucleotide sequence, in case that the clone has been obtained by hybridization, it is cultured, for example in a test tube to extract the plasmid according to a conventional method when the recombinant is E. coli. This plasmid is digested by a restriction enzyme to obtain a fragment for insertion. The fragment is subcloned into a vector such as M13 phage vector to determine the sequence by dideoxy method. When the recombinant is a phage, sequencing can be carried out basically in similar steps. These experimental methods from culture to nucleotide sequencing are described in, for example, T. Maniatis et al., Molecular Cloning A Laboratory Manual (1982) Cold Spring Harbor Laboratory.

To identify whether the gene obtained codes the desired almond N-glycosidase, the structure and the amino acid sequence can be known, by comparing the nucleotide sequence determined with the almond N-glycosidase gene of the present invention and with the amino acid sequence described in SEQ ID NO: 1.

When the gene which has been obtained does not contain the coding region of the N-glycosidase at all, the whole nucleotide sequence of the coding region which hybridizes to the almond N-glycosidase gene of the present invention can be determined by synthesizing DNA primers on the basis of the nucleotide sequence obtained to amplify the lacking portion by PCR, or by further screening the cDNA library using the fragment of the cDNA obtained as a probe.

To obtain a polypeptide having a N-glycosidase activity using genetic engineering, firstly, according to a standard method, the almond N-glycosidase gene is connected with a vector that can express them in a suitable host cell, for example bacteria such as E coli, Bacillus subtilis, yeasts, mammalian cells, insect cells, and plant cells. The recombinant vector is introduced into a host cell to prepare a recombinant cell. By culturing the recombinant cell, a polypeptide having a N-glycosidase activity can be produced. Alternatively, a polypeptide without sugar chain can be expressed by using cells as hosts which do not have an ability of synthesizing sugar chains, for example, procaryotes such as E. coli and Bacillus subtilis, or mutant cells of yeasts, mammalian cells, insect cells and plant cells, which have lost an ability of synthesizing sugar chains.

The polypeptide or the protein can be accumulated as an insoluble matter (inclusion body), depending on the expression system used. In this case, the activity can be recovered by collecting the insoluble matter, and solubilize it under a mild condition, for example with urea, then removing the denaturating reagent. The expression can be confirmed by assaying the almond N-glycosidase activity. For example, the assay can be carried out using dabsyl ovomucoid glycopeptide (manufactured by Genzyme) as a substrate according to the manual appended. That is, after incubation the enzyme solution with dabsyl ovomucoid at 37.degree. C., assay of the almond glycosidase activity can be performed by separating and detecting the dabsyl peptide produced by liberation of the sugar chain from the substrate, using reverse phase chromatography and thin layer chromatography.

To purify a polypeptide or a protein which has an almond N-glycosidase activity from the transformant, common chromatography techniques can be used. For example, when the cultured cells have been broken and the desired polypeptide has been solubilized, the desired polypeptide expressed can be obtained by subjecting the supernatant of the culture to chromatographies such as hydrophobic, ion exchange and gel filtration. When the expressed product is accumulated as an insoluble matter, the cells are broken, and the precipitation is collected to be solubilized with a denaturating reagent such as urea. Then, the polypeptide or the protein having the desired activity can be obtained after removing the denaturating reagent and refolding.

Thus, According to the present invention, a primary structure of an almond N-glycosidase gene is elucidated, and it is possible to provide a procedure of genetic engineering for preparing it. Also, similar N-glycosidase genes are provided using the genes of the present invention. Moreover, by said procedure of genetic engineering, it is possible to produce an almond N-glycosidase having no sugar chain.

The following Examples further illustrate the present invention in detail. However, they are not to construed to limit the scope of the present invention.

EXAMPLE 1

Cloning of cDNA of the Almond N-Glycosidase (1-1) Purification of the Almond N-Glycosidase

Two kg of a commercial almond meal (manufactured by Sigma) was emerged in 10 mM Bis-Tris buffer solution (pH 6.8) containing 2 mM phenyl metanesulfonyl fluoride (PMSF) and 1 mM 1,2-epoxy-3-(p-nitrophenoxy)propane (EPNP) with stirring for 20 hour at 5.degree. C., then the mixture was filtered through a filter cloth, and centrifuged to obtain a supernatant. After precipitating by adding ammonium sulfate to the supernatant to 80% saturation, dialysis of the precipitation was performed against 10 mM Mes buffer solution (pH 6.8). The dialyzed solution was applied to a column of an ion exchange resin DE52 (manufactured by Whatman) equilibrated with 10 mM Mes buffer solution (pH 6.8). The wash-through fraction with the same buffer solution was subjected to ion exchange chromatography on CM-Sepharose CL-6B (manufactured by Pharmacia), and eluted with a gradient of potassium chloride (0 to 0.5M). The active fraction eluted was dialyzed against 10 mM MOPS buffer solution (pH 7.0). A precipitation which generated during the dialysis was removed by centrifugation. The dialyzed solution was subjected to ion exchange column chromatography on Mono S (manufactured by Pharmacia), and eluted with a gradient of potassium chloride (0 to 0.4M). The active fraction eluted was dialyzed against 10 mM Tris buffer solution (pH 8.8). The dialyzed solution was subjected to ion exchange column chromatography on Mono Q (manufactured by Pharmacia), and eluted with a gradient of potassium chloride (0 to 0.5M). The active fraction eluted was diluted four times with 10 mM Tris buffer solution (pH 8.8). The diluted active fraction was again subjected to ion exchange column chromatography on Mono Q, and eluted with a gradient of potassium chloride (0 to 0.5M). After concentration of the active fraction eluted by ultrafiltration using Centricon 10 (manufactured by Amicon) of exclusive molecular weight 10000, the concentrate was subjected to gel permeation column chromatography on Superrose 12HR (manufactured by Pharmacia), and eluted with 10 mM Tris buffer solution (pH 8.8) containing 0.1M sodium chloride to obtain the active fraction. By above operations, the almond N-glycosidase was purified to a homogeneous protein. The purified almond N-glycosidase was composed of two polypeptide chains, a light chain and a heavy chain, which showed molecular weights 27000 and 60000 on SDS-PAGE, respectively.

(1-2) Analysis of the N-terminal Amino Acid Sequence and the Inner Partial Amino Acid Sequence

After dissociating the purified almond N-glycosidase to a light chain and a heavy chain by SDS-PAGE, these polypeptides were electrophoretically blotted (electroblotted) to a polyvinylidene difluoride (PVDF) membrane using Sartoblot II (manufactured by Sartorius), and sections containing the light chain and the heavy chain on the membrane were cut out separately to obtain samples for determination of the N-terminal amino acid sequences. The amino acid sequences of the samples prepared were determined from the N-terminal one after another by Edman method using a gas phase peptide sequencer (Model 477, manufactured by Applied Biosystem). The N-terminal amino acid sequence of the heavy chain obtained is shown in SEQ ID NO: 4, and that of the light chain is shown in SEQ ID NO: 30.

Determination of the inner amino acid sequence of the heavy chains was carried out as described below.

Firstly, the purified almond N-glycosidase as a sample was subjected to HPLC using an Asahipack C4-P50 column (manufactured by Asahi Kasei). By elution with a gradient of distilled water to acetonitrile containing 0.1% TFA, 500 pmol of the heavy chain was taken out, and solidified in a small sample tube under a reduced pressure. Then, the small sample tube containing the heavy chain was inserted into a test tube containing pyridine 5 .mu.l, 4-vinylpyridine 1 .mu.l, tributyl phosphine 1 .mu.l, and distilled water 5 .mu.l, and the test tube was sealed under vacuum. Then, by heating at 100.degree. for 5 minutes, cysteine residues in the heavy chain was pyridylethylated under gas phase. The heavy chain thus S-pyridylethylated was dissolved in 50 .mu.l of 10 mM Tris buffer solution (pH 9.0). One pmol of lysyl endopeptidase (manufactured by PIERCE) was added to the mixture, and digestion was carried out at 37.degree. C. for 7 hours. Then, the digested sample. was subjected to HPLC using a Cosmosil 5C18AR column (manufactured by Nakarai). Purification of the peptide fragment was carried out by eluting with a gradient of distilled water containing 0.1% TFA to acetonitrile containing 0.05% TFA.

The peptide fragments obtained were analyzed by a gas phase peptide sequencer (Model 477, manufactured by Applied Biosystems) to determine the inner amino acid sequence of the heavy chain shown in SEQ ID NO: 7-14.

(1-3) Extraction of mRNA and Synthesis of cDNA

Almond fruits were harvested, and soon freezed at -80.degree. C. to be stored. Seven stored fruits were broken in frozen state, and the seeds were separated from the pulp. The seeds were milled with liquid nitrogen in a mortar, and the whole RNA was extracted using a RNA extraction kit (manufactured by Amersham) according to the manual to obtain 176 .mu.g of whole RNA. The whole RNA was treated with Oligotex dT 30 (manufactured by Takara Shuzo Co., Ltd.) to obtain 2.9 .mu.g of poly(A)RNA. Using 0.7 .mu.g of this poly(A)RNA as a template and using a cDNA synthesis kit (manufactured by Amersham), for first strand cDNA synthesis, priming was accomplished by d(T).sub.20 M4 shown in SEQ ID NO: 18.

(1-4) Amplification of the N-terminal of the Heavy Chain by PCR

Primers shown in SEQ ID NO: 5, 6 and 15-17 were designed from the N-terminal amino acid sequence and the inner amino acid sequence of the heavy chain determined in Example 1 (1-2), and synthesized by a DNA synthesizer (Model 394, manufactured by Applied Biosystems).

That is, sense mixed primers HNT1 and HNT2 shown SEQ ID NO: 5 and 6 respectively which correspond to amino acids 3-9 and 8-14 respectively of the N-terminal sequence of the heavy chain shown in SEQ ID NO: 4; an anti sense mixed primer HIC1 shown in SEQ ID NO: 15 which corresponds to amino acids 12-19 of the inner sequence of the heavy chain shown in SEQ ID NO: 7; and anti sense mixed primers HIC2 and HIC3 shown in SEQ ID NO: 16 and 17 respectively which correspond to amino acids 12-19 and 2-8 respectively of the inner sequence of the heavy chain shown in SEQ ID NO: 11 were synthesized. Using these primers, nested PCR reaction was carried out.

The primary PCR was carried out in a mixture, which was prepared by taking 1/20 of the cDNA (1 .mu.l) as a template prepared in Example 1 (1-3) into a 0.5 ml tube for PCR, and adding 10 .mu.l of 10.times. buffer solution contained in GeneAmp.TM. PCR reagent kit (manufactured by Takara Shuzo Co., Ltd.), 16 .mu.l of 1.25 mM dNTP mixture, 1 .mu.l of the sense mixed primer (500 pmol/.mu.l), 1 .mu.l of the anti sense mixed primer (500 pmol/.mu.l), 0.5 .mu.l of 5 units/.mu.l AmpliTaq.TM., and sterilized water to 100 .mu.l. After overlaying 100 .mu.l of mineral oil (manufactured by Sigma) on this solution, PCR reaction was carried out by an automatic gene amplifier (Thermal cycler, manufactured by Takara Shuzo Co., Ltd.). The amplification was performed in using the program set to denaturate at 94.degree. C. or 2 minutes for a cycle, denature at 94.degree. C. for 1 minute, anneal at 55.degree. C. for 2 minutes and extend at 55.degree. C. for 2 minutes for a total of 30 cycles, then elongate at 60.degree. C. for 7 minutes. In this case, the PCR was carried out using three combinations of a sense mixed primer and an anti sense mixed primer, that is, HNT1 and HIC1, HNT1 and HIC2, and HNT1 and HIC3. These reaction mixtures were named PCR1, PCR2 and PCR3, respectively.

Then, using these reaction mixtures, the secondary PCR was carried out. Using these three reaction mixtures as templates (each 1 .mu.l), the secondary PCR was carried out under the same conditions as the primary PCR using three combinations of a sense mixed primer and an anti sense mixed primer, that is, HNT2 and HIC1, HNT2 and HIC2, and HNT2 and HIC3. The reaction mixtures obtained were named PCR1-1, PCR1-2, PCR1-3, PCR2-1, PCR2-2, PCR2-3, PCR3-1, PCR3-2 and PCR3-3. After reactions, upper mineral oil was removed, then 5 .mu.l of each reaction mixture was resolved on an agarose gel electrophoresis, and visualized by ethydium bromide fluorescence to confirm the products amplified. From the results, a specific amplification of DNA was found in PCR2-2. This amplified DNA fragment of approximately 500 bp was named FHN.

(1-5) Determination of the Nucleotide Sequence of the N-Terminal Portion of the Heavy Chain

The remainder of the reaction mixture from Example 1 (1-4) was concentrated by precipitation with ethanol, and the whole precipitation was subjected to agarose gel electrophoresis. After staining with ethydium bromide, a section containing the desired FHN DNA fragment was cut out from the gel under ultraviolet, and the DNA fragment was extracted and purified from the portion using EASYTRAP.TM. (manufactured by Takara Shuzo Co., Ltd.). Then, after phosphorylation of the 5'-terminal thereof using MEGALABEL.TM. (manufactured by Takara Shuzo Co., Ltd.), it was blunt-ended using DNA Blunting Kit (manufactured by Takara Shuzo Co., Ltd.), and ligated to the Hinc II-digested pUC19 plasmid using DNA Ligation Kit (manufactured by Takara Shuzo Co., Ltd.). Using an aliquot of the ligation reaction mixture, E. coli strain JM109 was transformed to obtain a recombinant E. coli containing the FHN DNA fragment amplified by PCR in the Hinc II site.

Four clones of the recombinant E. coli obtained were cultured in liquid medium, and the plasmid DNAs were prepared by alkaline lysis method. These four inserted fragments in the plasmids were named FHN1, FHN2, FHN3 and FHN4, and the whole sequences thereof were determined by dideoxy method. Each sequence is shown in SEQ ID NO: 19-22. In each sequence, nucleotides 1-20 was from the sense mixed primer HNT2, nucleotides 466-485 was from the anti sense mixed primer HIC2. When the whole nucleotide sequences of the inserted fragments were translated into amino acids, they coincided well with the N-terminal sequence (SEQ ID NO: 4) and the inner sequence (SEQ ID NO: 11) of the heavy chain. However, among the nucleotide sequences of FHN1 to FHN4, differences were found at nucleotides 22, 36, 39, 170 and 245.

(1-6) Amplification of the cDNA of the C-Terminal Portion of the Heavy Chain by PCR

Primers shown in SEQ ID NO: 23 and 24 were designed from the N-terminal portion of the heavy chain determined, and synthesized by a DNA synthesizer. That is, sense primers HI1 and HI2, shown in SEQ ID NO 23 and 24 respectively which correspond to nucleotides 72-95 and 148-164 of FHN1 to FHN4 shown in SEQ ID NO: 19-22, were synthesized. Also, PCR was carried out using a synthesized DNA M13 primer M4 (SEQ ID NO: 25) as an anti sense primer which has the same nucleotide sequence as nucleotides 1-17 of d(T).sub.20 M4 (SEQ ID NO: 18). Using these primers, nested PCR was carried out.

Firstly, the primary PCR was carried out as follows: 16 .mu.l of 1.25 mMdNTP mixture, 1 .mu.l of 10 pmol/.mu.l HI1, and 1 .mu.l of 100 pmol/.mu.l M13 primer M40 were taken into a 0.5 ml tube for PCR, and a pellet of AmpliWax.TM. PCR Gem100 (manufactured by Takara Shuzo Co., Ltd.) was added thereto, then the mixture was incubated at 80.degree. C. for 6 minutes. Then, by incubating the mixture at 25.degree. C. for 2 minutes to form a wax layer. Further, after adding 1/20 (1 .mu.l) of the cDNA prepared in Example 1 (1-3) as a template, 0.5 .mu.l of 5 units/.mu.l AmpliTaq.TM., 10 .mu.l of 10 X buffer solution for amplification, and 70.5 .mu.l of sterilized water, PCR was carried out by an automatic gene amplifier (thermal cycler) (hereinafter, referred this PCR method as Hot Start PCR method). The reaction was carried out as follows: after melting the wax and mixing the upper and lower layers at 94.degree. C. for 2 minutes, a cycle, which consists of denaturation at 94.degree. C. for 1.5 minutes, annealing of the primer at 55.degree. C. for 1 minute, extension at 72.degree. C. for 2.5 minutes, was repeated 30 times, then further elongation at 60.degree. C. for 7 minutes and solidification of the wax at 4.degree. C. were carried out.

The secondary PCR was carried out under the same conditions as the primary PCR using 1 .mu.l of the reaction mixture from the primary PCR and 1 .mu.l of 100 pmol/.mu.l HI2. After the reaction, 5 .mu.l of the reaction mixture was subjected to agarose gel electrophoresis, and the DNAs were stained with ethydium bromide. A band of the approximately 1.2 Kbp cDNA of the almond N-glycosidase which contains the C-terminal portion of the heavy chain amplified specifically was confirmed. This DNA fragment amplified by PCR was named FHC.

(1-7) Determination of the Nucleotide Sequence of the C-Terminal Portion of the Heavy Chain

The remainder of the reaction mixture from Example 1 (1-6) was purified as Example 1 (1-4), and ligated to the Hinc II-digested pUC19 plasmid. By this plasmid, E. coli strain JM109 was transformed to obtain a recombinant E. coli containing FHC DNA fragment amplified by PCR in the Hinc II site.

Four clones of the recombinant E. coli obtained were cultured in liquid medium, the plasmid DNAs were prepared by alkali lysis method. These four fragments inserted in the plasmids were named FHC1, FHC2, FHC3 and FHC4, respectively. To determine the whole nucleotide sequences from these inserted fragments, each plasmid was digested by restriction endonucleases Pst I and Hind III. After subjecting the DNA fragments obtained to agarose gel electrophoresis, the DNA fragments were ligated to the Pst I or Hind III-digested M13P18 or M13P19, and E. coli JM109 were transformed with the ligation mixtures. Further, the recombinant E. coli were cultured to prepare ssDNA. These DNAs were sequenced by dideoxy method, and by joining these sequences the whole nucleotide sequences of FHC1, FHC2, FHC3 and FHC4 were determined. Each sequence is shown in SEQ ID NO: 26-29. When the whole nucleotide sequences of the inserted fragments were translated into amino acid sequences, these fragments contained coding region of the C-terminal and a non-translated region of the heavy chain, and coincided well with the inner amino acid sequences of the heavy chain (SEQ ID NO 7-14). Comparing the nucleotide sequences of FHC1 to FHC4 one another, FHC1 has the same nucleotide sequence as FHC3, and the others have differences in nucleotides 98, 464, 500, 794, 823, 877, 884 and 891.

The 139 bp of the 5'-termini of FHC1 to FHC 4 overlapped the 139 bp of the 3'-termini of FHN1 to FHN4. Thus, the whole sequence of the heavy chain cDNA was determined by FHN1 to FHN4 and FHC1 to FHC4.

(1-8) Amplification of the cDNA of the Light Chain

Sense mixed primers shown in SEQ ID NO: 31-34 were designed from the N-terminal partial DNA sequence of the light chain determined in Example 1 (1-2), and anti sense primers were designed from the cDNA sequence of the heavy chain determined in Example 1 (1-2) and (1-3). These primers were synthesized by a DNA synthesizer and purified. That is, as sense mixed primers, primers LN1C and LN1T shown in SEQ ID NO: 31-32 respectively which correspond to the amino acids 1-8 of the N-terminal sequence of the light chain; primer LN2 shown in SEQ ID NO: 33 which corresponds to amino acids 6-12; and primer LN3 shown in SEQ ID NO: 34 which corresponds to amino acids 12-18 were synthesized. Also, as an anti sense primer, primer HIC4 shown in SEQ ID NO: 35 which corresponds to nucleotides 262-286 of SEQ ID NO: 19-22 and nucleotides 125-149 of SEQ ID NO: 26-29 was synthesized. Using these primers, nested PCR was carried put.

According to hot start PCR above described, amplification by the primary PCR was carried out using 1/20 (1 .mu.l) of the cDNA as a template prepared in Example 1 (1-3). The reaction was conducted under following conditions: after melting the wax and mixing the upper and lower layers at 94.degree. C. for 2 minutes, a cycle, which consists of denaturation at 94.degree. C. for 1 minute, annealing of the primer at 55.degree. C. for 1 minute, extension at 72.degree. C. for 2.5 minutes, was repeated 30 times, then further elongation at 60.degree. C. for 7 minutes and solidification of the wax at 4.degree. C. were carried out. In this case, using three combinations of sense mixed primers and an anti sense primer, LN1C and HIC4, LN1T and HIC4, and LN2 and HIC4, the PCR was carried out. The reaction mixtures were named PCR4, PCR5 and PCR6, respectively. Then, the secondary PCR was carried out using these three reaction mixtures (each 1 .mu.l) as templates. To templates PCR4 and PCR5, using two combinations of a sense mixed primer and an anti sense mixed primers, that is, LN2 and HIC4, and LN3 and HIC4, and To PCR6, using a combination of LN3 and HIC4 the PCR was carried out under the same conditions as the primary PCR. The reaction mixtures were named PCR4-1, PCR4-2, PCR5-1, PCR5-2 and PCR6-1. 5 .mu.l of the each reaction mixture was subjected to agarose gel electrophoresis, and the DNA were stained with ethydium bromide to identify the products amplified. From the results, amplification of the specific DNA of the same size was found in PCR4-1 and PCR5-1. This amplified DNA fragment of about 900 bp was named FL.

(1-9) Determination of the cDNA Nucleotide Sequence of the Light Chain

After concentration of the whole reminder of the PCR by ethanol precipitation, the concentrate was subjected to agarose gel electrophoresis to isolate fragment FL. Fragment FL was phosphorylated at the 5'-terminal and blunt-ended, then ligated with the Hinc II-digested pUC19 plasmid. Using an aliquot of the ligation reaction mixture, E. coli strain M109 was transformed to obtain a recombinant E. coli containing FL DNA fragment amplified by PCR in the HincII site.

Six clones of the recombinant E. coli were cultured in liquid medium, and plasmid DNAs were prepared by alkali lysis method. These six inserts in the plasmid DNA were named FL1, FL2, FL3, FL4, FL5 and FL6, respectively.

In order to determine the whole nucleotide sequences of these inserts, a plasmid which lacked an EcoRI fragment of about 380 bp was prepared after digestion of each plasmid by a restriction enzyme Eco RI. Also, a plasmid lacking a fragment of about 220 bp was prepared by a restriction enzyme Pst I. These plasmids were sequenced by dideoxy method, and these sequences were connected together to determine the whole nucleotide sequences of FL1, FL2, FL3, FL4, FL5 and FL6. Each sequence is shown SEQ ID NO: 36-41.

Nucleotides 1-20 in sequences of FL1-FL6 (SEQ ID NO: 36-41) was the sequence from the sense mixed primer LN2 (SEQ ID NO: 33). Nucleotides 499-774, and nucleotides 626-774 coincided well with nucleotides 1-276 of the PCR fragment FHN1-FHN4 (SEQ ID NO: 19-22) of the N-terminal portion of the heavy chain, and with nucleotides 1-149 of the PCR fragment FHC1-FHC4 (SEQ ID NO: 26-29) of the N-terminal portion of the heavy chain, respectively. These relationships are shown in FIG. 1. Further, when the whole nucleotide sequences of FL1-FL6 (SEQ ID NO: 36-41) were translated into amino acid sequences, it was found that they contained a sequence coinciding well with the N-terminal sequence of the light chain (SEQ ID NO: 30) and the N-terminal sequence of the heavy chain (SEQ ID NO: 4) determined in Example 1 (1-2). Thus, it was found that the amino acid sequences of the light chain and the heavy chain were coded in the same frame on a cDNA. By comparing with FL1-FL6 (SEQ ID NO: 36-41) one another, it was found that FL1 and FL3, and FL4 and FL6 contained the same nucleotide sequences, respectively, and that the others were different at nucleotides 205, 439, 520 and 723 one another.

This fragment was extracted from the gel and purified. This fragment was inserted to a Xba I-Kpn I site of a plasmid pTVl119N (manufactured by Takara Shuzo Co., Ltd.) to obtain a plasmid pTANG-HC. The plasmid containing FL1 (SEQ ID NO: 36) obtained in Example 1 (1-9) was digested by restriction enzymes Nde I and Xba I. Agarose gel electrophoresis was conducted, and a portion of the gel containing a fragment FL1-Nde I/Xba I of about 660 bp was cut out, and the fragment was extracted from the gel.

Further, pTANG was digested by restriction enzymes SacI and BamHI, and agarose gel electrophoresis was conducted. A portion of the gel, which contained a fragment TANG-SacI/BamHI of about 1.6 kbp containing from the mature N-terminal of the almond N-glycosidase gene to the whole length thereof, was cut out, and the fragment was extracted from the gel. This fragment TANG-Sac I/Bam HI and a plasmid pET23a (manufactured by Novagen) were digested by Sac I and Bam HI, and then dephosphorylated. By ligation of these fragments, a plasmid pETANG was obtained. pETANG was digested by restriction enzymes Bam HI and Xho I, then blunted by a DNA blunting kit.
