Biochem/physiol Actions
Mode of Action: Inhibits protein synthesis (elongation) by interfering with peptidyl tRNA translocation.
Antimicrobial spectrum: Gram-negative and Gram-positive bacteria (Gonnococcus only).
Mode of Resistance: Mutation in rpsE (the gene for ribosomal protein S5) prevents binding of spectinomycin.
用途:抗菌素,是蛋白质合成抑制剂;靠干扰肽基tRNA转录抑制蛋白合成,起到抑菌作用。对象为革兰氏阴性和阳性菌。抑制模式:rpsE(核糖体蛋白S5基因)基因的变异能阻止大观霉素的结合。
溶液配制:可溶于水(10MG/ML),溶解后,过滤除菌,4℃保存数周,-20℃保存1-3年。
