RECOMBINANT COMAMONAS TESTOSTERONI 5-MGAM-4D; AMIDS AND CARBOXYLIC ACID PRODUCTION

摘要

The invention relates to the isolation, sequencing, and recombinant expression of genes encoding either a nitrile hydratase (NHase) or amidase (Am) from Comamonas testosteroni 5-MGAM-4D, where the NHase is useful for catalyzing the hydration of certain nitriles to the corresponding amides, and the amidase is useful for hydrolysis of certain amides to the corresponding carboxylic acids. Also provided are transformed host cells containing polynucleotides for expressing the nitrile hydratase or amidase enzymes from Comamonas testosteroni 5-MGAM-4D.
