[Aminoacylase from Streptoverticillium microorganisms: stereo- and substrate specificity].
1984
: The stereo- and substrate specificity of a new aminoacylase from Streptoverticillium microorganisms was studied. The enzyme effectively hydrolyzes acetyl derivatives of aliphatic (methionine, leucine) and aromatic (phenylglycine, phenylalanine, tryptophan) amino acids. The L-enanthiomer of acetylphenylglycine is hydrolyzed by aminoacylase 8000 times more effectively than the D-enanthiomer. A procedure for determination of the enanthioselectivity of aminoacylases was elaborated. This procedure is designed for a detection and assessment of contaminations of the N-acetyl derivative of one enanthiomer by another enanthiomer of the amino acid, as well as of the degree of racemization of the substrate during hydrolysis of acetyl derivatives of D-amino acids.
