(S)-2-aminohexano-6-lactam = (R)-2-aminohexano-6-lactam
D- and L-amino acids are produced from L- and D-amino acid amides by D-aminopeptidase from Ochrobactrum anthropi C1-38 and L-amino acid amidase from Pseudomonas azotoformans IAM 1603, respectively, in the presence of alpha-amino-epsilon-caprolactam racemase from Achromobacter obae. Substrate: L-alanine amide, product: D-alanine (100% yield), substrate: L-2-aminobutyric amide, product: D-2-aminobutyric acid (100% yield), substrate: L-serine amide, product: D-serine (94% yield), substrate: L-methionine amide, product: D-methionine (100% yield), substrate: D-alanine amide, product: L-alanine (100% yield), substrate: D-leucine amide, product: L-leucine (100% yield), substrate: D-methionine amide, product: L-methionine (100% yield)
