Inhibits protein synthesis by binding to L6 protein of 50S ribosomal subunit. Antibacterial.\nAntibiotic complex consists of three closely related components, gentamicins C1, C2, C1a, and also gentamicin A which differs from the other members of the complex but is similar to Kanamycin C.\nGentamicin C1: R1=R2=CH3\nGentamicin C2: R1=CH3; R2=H\nGentamicin C1A: R1=R2=H

用途
用途庆大霉素靠结合到30S核糖体亚单位上引起密码读错,阻断肽酰-tRNA(peptidyl-tRNA)从受体位点到供体点点的转移。庆大霉素对假单胞杆菌的杀菌效果靠结合到细胞膜的外膜部分,置换本来存在的阳离子,使膜不稳定,在细胞表面形成空洞。抗菌谱: 革兰氏阴性细菌,葡萄状球菌和其它的革兰氏阳性细菌。
