Claims
- 1. An isolated DNA.sup.(H) fragment encoding a polypeptide having nitrile hydratase activity, said polypeptide consisting of a an .alpha..sup.(H) -subunit and .beta..sup.(H) -subunit, wherein the isolated DNA fragment consists of a 1970 kb DNA fragment having the nucleotide sequence of SEQ ID: No. 14.
- 2. A DNA comprising DNA.sup.(H) of claim 1 in a recombinant cloning vector.
- 3. A transformed cell containing the recombinant DNA of claim 2.
- 4. A method of producing nitrile hydratase which comprises culturing the transformant as claimed in claim 3 which is a prokaryote transformant and recovering nitrile hydratase from the culture.
- 5. A method of producing amides which comprises hydrating nitriles using nitrile hydratase obtained from the culture of the transformant of claim 3.
- 6. A method of producing amides which comprises culturing the transformant as claimed in claim 3, and hydrating nitriles to amides using the resultant culture, isolated bacterial cells, the supernatant of the culture, an extract of the culture, or a fixed material thereof.
- 7. A method of producing nitrile hydratase which comprises culturing a transformed cell containing the plasmid of claim 2, in the presence of cobalt, wherein the transformed cell is a prokaryotic cell, and recovering nitrile hydratase from the culture.
- 8. An isolated DNA.sup.(L) fragment encoding a polypeptide having nitrile hydratase activity, said polypeptide consisting of an .alpha..sup.(L) -subunit and .beta..sup.(L) -subunit, wherein the isolated DNA fragment consists of a 1730 kb DNA fragment having the nucleotide sequence SEQ. ID. No. 15.
- 9. A DNA comprising DNA.sup.(L) of claim 8 in a recombinant cloning vector.
- 10. A transformed cell containing the recombinant DNA of claim 9.
- 11. A method of producing nitrile hydratase which comprises culturing the transformant as claimed in claim 10 which is a prakoaryote transformant and recovering nitrile hydratase from the culture.
- 12. A method of producing amides which comprises hydrating nitriles using nitrile hydratase obtained from the culture of the transformant of claim 10.
- 13. A method of producing amides which comprises culturing the transformant as claimed in claim 10, and hydrating nitriles to amides using the resultant culture, isolated bacterial cells, the supernatant of the culture, an extract of the culture, or a fixed material thereof.
- 14. A method of producing nitrile hydratase which comprises culturing a transformed cell containing the DNA of claim 9, in the presence of cobalt, wherein the transformed cell is a prokaryotic cell, and recovering nitrile hydratase from the culture.
