Biochem/physiol Actions
Aminoglycosides, such as ribostamycin, bind to the bacterial 30S and 50S ribosomal subunit, which inhibits the translocation of the peptidyl-tRNA from the A-site to the P-site. This causes misreading of mRNA which makes bacteria unable to make essential proteins. It also inhibits the chaperone activity of protein disulfide isomerase (PDI).

性状：常用其硫酸盐，为白色粉末，味微苦，易溶于水。

作用：抗菌谱与卡那霉素近似，对葡萄球菌、链球菌、肺炎球菌、大肠杆菌和部分的变形杆菌菌株有效，抗菌作用较卡那霉素略弱。本品对绿脓杆菌、结合杆菌无效。
