title: [Isolation of a highly pure preparation of cephalexin amidase from bacteria of the genus Xanthomonas].
abstract: A procedure for highly purified cephalexin amidase of Xanthomonas was developed. It consists of preparation of a cell-free extract of the culture after cell disintegration, precipitation with ammonium sulfate, dissolution, concentration and elimination of ballast proteins, gel filtration on Sephadex G-25, sorption of ballast proteins on DEAE cellulose and chromatography on KM-cellulose. The enzyme yield is 45-55 per cent. The purity level is 80-90-fold.
