ABSTRACT:
350 The present invention provides a nitrile hydratase nucleic acid fragment isolated from Pseudomonas putida which encodes a nitrile hydratase activity capable of catalyzing the hydrolysis of certain racemic nitriles to the corresponding R- or S-amides. Also provided are transformed microorganisms capable of the active expression of said nitrile hydratase activity. Additionally, the invention provides a transformant harboring the nitrile hydratase gene in conjunction with an amidase gene, both of which may be co-expressed producing active nitrile hydratase and amidase enzymes respectively. Methods for the production of such enantiomeric materials are also provided.
