1FM2 - PubMed Abstract: 
Semisynthetic cephalosporins are primarily synthesized from 7-aminocephalosporanic acid (7-ACA), which is usually obtained by chemical deacylation of cephalosporin C (CPC). The chemical production of 7-ACA includes, however, several expensive steps and requires thorough treatment of chemical wastes. Therefore, an enzymatic conversion of CPC to 7-ACA by cephalosporin acylase is of great interest. The biggest obstacle preventing this in industrial production is that cephalosporin acylase uses glutaryl-7ACA as a primary substrate and has low substrate specificity for CPC.
