Cephalosporin C (CPC) was the second [beta]-lactam antibiotics to be discovered after penicillin from the fungus Cephalosporium acremonium by Giuseppe Brotzu (1,2).
According to the diversity in substrate specificity, CAs can be divided into two classes, the cephalosporin C (CPC) acylase and the glutaryl-7-aminocephalosporanic acid (GL-7-ACA) acylase classes.
The types of cephalosporin acylase are: type 1 is true cephalosporin C acylase.
The natural of cephalosporin C acylase catalyzed the CPC to 7-ACA directly in a very low efficiency (14,15,16), significant substrate inhibition (14), and product inhibition (14).
The biotransformation of cephalosporin C to 7-ACA in one step enzymatic with cephalosporin acylase is a simple process with low cost and potential to applied in industrial production.
The protein engineering of cephalosporin C acylase was developed to increase its activity and stability of CPC acylase.
