Abstract

An enzyme is provided which has acylase activity capable of hydrolyzing N-acetyl-(R,S)-pipecolic acid stereoselectively to give (S)-pipecolic acid, wherein this activity is greater than that on N-acetyl-S-proline, at pH 7.5, 25.degree. C., and substrate concentration 20 g/l, in 75 mM Tris buffer. The enzyme is obtainable from the species of Alcaligenes denitrificans deposited as NCIMB 40587. A microorganism having therein the enzyme also is provided, as is a process for preparing (S)-pipecolic acid comprising contacting a mixture of enantiomers of an N-acyl-pipe colic acid with the enzyme or microorganism.
