  • DNA encoding polypeptide having nitrile hydratase activity and method for producing amides from nitriles with transformant containing the same
    Patent number: 5130235
    Abstract: A DNA which encodes polypeptide carrying two specific amino acid sequences and having nitrile hydratase activity; a method for producing nitrile hydratase by incubating a transformant made by the transformation with a recombinant DNA prepared by integrating the foregoing DNA into a vector in a medium and harvesting nitrile hydratase accumulated in the medium; and a method for producing amides by incubating the foregoing transformant and then converting nitriles into corresponding amides by the action of the obtained nitrile hydratase or by making a culture solution, isolates, treated cells or their immobilized products act upon nitriles to produce corresponding amides.
