    摘要: A cephalosporin C acylase from Pseudomonas diminuta N-176 is characterized by its ability to catalyze the conversion of cephalosporin C, glutaryl 7-ACA, adipyl 7-ACA, succinyl 7-ACA, N-acetylcephalosporin, N-benzoylcephalosporin C and cephalothin into 7-aminocephalosporanic acid. The enzyme contains an .alpha.-subunit having a molecular weight of 26 kDA and a .beta.-subunit having a molecular weight of 58 kDa. A method for the recombinant production of the present cephalosporin C acylase in Escherichia coli is provided.
