bacitracin

antibioticmech:aro-736d7660a3 ·ANTIBACTERIAL ·MINTED SEEDED

Bacitracin is a mixture of related cyclic polypeptides produced by organisms of the licheniformis group of Bacillus subtilis var Tracy. Bacitracin interferes with the dephosphorylation of the C55-isoprenyl pyrophosphate, a molecule which carries the building blocks of the peptidoglycan bacterial cell wall outside of the inner membrane. — PMID:8389741
