Gene encoding one step cephalosporin C amidase and expression thereof in recombinant bacillus

摘要

A process for the one-step conversion of cephalosporin C and derivatives thereof to the corresponding 7-aminocephalosporanic acid and derivatives comprising treating said cephalosporin C and derivatives with a cephalosporin C amidase enzyme of a recited sequence, the DNA encoding said enzyme, and expression thereof in a suitable host, e.g., Bacillus species under the control of a suitable promoter.
