The thiopeptides, by binding within a cleft located between the ribosomal protein L11 and helices 43 and 44 of the 23S rRNA, overlap with the position of domain V of EF-G, thus explaining how this class of drugs perturbs translation factor binding to the ribosome.

核糖体蛋白L11和23SrRNA的43/44螺旋结构形成裂隙，L11的构象变化能够加宽该裂隙从而允许延伸因子EF-G插入，促使GTP水解，为肽链延伸合成过程中核糖体的构象变化提供能量，而Thio能够与L11和23sRNA结合，阻止L11的构象变化，使该裂隙处于闭合状态，抑制EF－G在延伸过程中的作用。
