ABSTRACT:
The invention provides a glutaryl 7-ACA amidase fromPseudomonas diminutastrain BS-203, which catalyzes the hydrolysis of 7-β-(4-carboxybutanamido)-cephalosporanic acid to 7-aminocephalosporanic acid and glutaric acid. The invention also provides nucleic acid sequences, vectors, and host cells useful in the production of this amidase. The glutaryl 7-ACA amidase can be used for the preparation of 7-aminocephalosporanic acid.
