Antimicrobial spectrum: Gram-positive bacteria.
Bacitracin inhibits bacterial cell wall synthesis by inhibiting dephosphorylation of lipid pyrophosphate.

Used to study dysruption of bacterial cell wall synthesis at the level of peptidoglycan biosynthesis and isoprenyl metabolism.

性状及说明：类白色或淡黄色的粉末；无臭，味苦；有引湿性；易被氧化剂破坏，在溶液中能被多种重金属盐类沉淀。本品在水中易溶，在乙醇中溶解，在丙酮、氯仿或乙醚中不溶, 抗菌谱与青霉素相似，对革兰阳性细菌和阴性球菌、肺炎双球菌、葡萄球菌、淋球菌、脑膜炎双球菌及螺旋体等均有杀菌作用。其作用机制不仅作用于细胞壁，也影响原生质体，对胞浆膜也有损坏作用，影响其渗透性。
