Penicillin-binding proteins (PBPs) function in the late steps of murein biosynthesis. PBP-2B is required for vegetative cell division and sporulation septation. Beta-lactamase inactivates the PBPs by acylating an essential serine residue in the active site of these proteins, thereby interrupting normal cell wall synthesis (Probable). This protein itself, but not its transpeptidase activity, is required for cell division (PubMed:28792086).Curated1 Publication
