| Enzyme Function | FUNCTION: Penicillin-binding protein with an unknown catalytic activity. Penicillin-binding proteins (PBPs) function in the late steps of murein biosynthesis. Beta-lactamase inactivates the PBPs by acylating an essential serine residue in the active site of these proteins, thereby interrupting normal cell wall synthesis. |
