ISOLATION AND EXPRESSION OF A GENE FOR A NITRILASE FROM i ACIDOVORAX FACILIS 72W

摘要

Recombinant microbial strains are provided that express nitrilase enzyme and are useful as biocatalysts for the hydrolysis of nitrile-containing substrates. The recombinant cells are transformed with a foreign gene isolated from Acidovorax facilis 72W encoding a thermostable nitrilase enzyme that catalyzes the hydrolysis of nitrile-containing substrates to carboxylic acids under mild reaction conditions. The nucleotide sequence of the nitrilase gene and the deduced amino acid sequence encoded by the nitrilase gene are provided.
