Abstract

The disclosure provides a nitrilase from, which belongs to genus, family brassicaceae. The disclosure further provides the encoding gene, vector, recombinant bacterial strain, and the application in the manufacturing of (S)-3-cyano-5-methylhexanoic acid. The wet resting cells containing nitrilase Aa-Nit can kinetically resolve racemic IBSN at 1.2 M with a 42% conversion rate in 15 hr and >99% ee value. The disclosure provides a regio- and stereoselective method for the preparation of (S)-3-cyano-5-methylhexanoic acid. This method provides an atom economical, mild, environmental friendly industrial method to manufacture (S)-3-cyano-5-methylhexanoic acid.
