Abstract
A novel N-Acetyl-2,3-didehydroaminoacid-acylase is obtained by cultivating Zoogloea ramigera DSM 4306. The new enzyme can be used in a coupled enzyme system with an L-Leucinedehydrogenase for the enzymatic conversion of N-Acetyl-2,3-didehydroleucine to L-Leucine, D- or L-tryptophylglycine to D- or L-tryptophaneamide and glycine, as well as other tryptophanedipeptides to tryptophaneamides and free amino acids.
