General FunctionSerine-type d-ala-d-ala carboxypeptidase activity
Specific FunctionCatalyzes distinct carboxypeptidation and transpeptidation reactions during the last stages of wall peptidoglycan synthesis. Mistaking a beta-lactam antibiotic molecule for a normal substrate (i.e. a D-alanyl-D-alanine-terminated peptide), it becomes immobilized in the form of a long-lived, serine-ester-linked acyl enzyme and thus behave as penicillin-binding protein (PBP).
