    Abstract: Isolated nucleic acid (I), encoding a polypeptide (II) with nitrilase activity, is (i) a 1483 bp sequence (1), reproduced; (ii) a sequence equivalent to (1) within the degeneracy of the genetic code or (iii) a derivative of (1) that encodes a polypeptide having at least 95% homology with a 366 amino acid polypeptide (2), reproduced, and essentially the same enzymatic activity as (2). Independent claims are also included for the following: (a) (II) encoded by (I); (b) nucleic acid construct containing (I) linked to one or more regulatory signals; (c) vector containing (I) or the construct of (b); (d) recombinant microorganism containing (I), the construct of (b) or the vector of (c); and (e) method for producing achiral or chiral carboxylic acids (III) by treating nitriles (IV) with (II) or with growing, resting or lysed microorganisms of (d).

    Abstract: An isolated nucleic acid sequence (I) encoding an Alcaligenes faecalis nitrilase polypeptide is new. An isolated nucleic acid sequence (I) encoding a polypeptide with nitrilase activity is selected from: (1) a defined genomic DNA sequence (seq1) of 1071 base pairs (bp) given in the specification; (2) nucleic acid sequences derived from seq1 as a result of the degeneracy of the genetic code; and (3) derivatives of seq1 that code for a polypeptide with a defined sequence of 356 amino acids and have at least 95% homology at the amino acid level without essentially reducing the enzymatic activity of the polypeptide (sic). Independent claims are also included for: (1) an amino acid sequence encoded by (I); (2) a nucleic acid construct (II) comprising (I) linked to one or more regulatory sequences; (3) a vector containing (I) or (II); (4) a microorganism containing (I) or (II); (5) a process for preparing chiral carboxylic acids of formula (III), comprising converting a racemic nitrile of formula (IV) in the presence of an amino acid sequence as in (1) or a growing, resting or digested microorganism as in (4), where the nitrile conversion is at least 25 mmoles/hour per mg protein or 25 mmoles/hour per g dry weight. R -R = H, optionally substituted 1-10C alkyl, 2-10C alkenyl, optionally substituted aryl, heteroaryl, OR or NR R , provided that R -R are all different; R = H, optionally substituted 1-10C alkyl, 2-10C alkenyl, 2-11C alkanoyl, 3-11C alkenoyl, aryl, aroyl, heteroaryl or heteroaroyl; and R = H, optionally substituted 1-10C alkyl, 2-10C alkenyl, aryl or heteroaryl.
