一般描述

一种从链霉菌属远青链霉菌中分离出来的含噻唑多肽抗生素。通过与50S亚基GTPase中心的23S rRNA非共价，但几乎不可逆地结合，抑制细菌蛋白质合成和核糖体GTPase活性。硫链丝菌素结合直接阻止与延伸因子G（EF-G）核糖体的结合，延伸因子G也与23S rRNA特异性结合。硫链丝菌素已被证明在阐明翻译的分子机制，特别是核糖体易位的分子机制方面很有用。它还用于在链霉菌属细菌中选择含有tsr基因（蓝色链霉菌）的载体，该基因编码23S rRNA甲基化酶，其作用阻止硫链丝菌素与核糖体结合。
一种含噻唑的肽抗生素，通过阻止GTP与50S核糖体亚单位的结合来抑制蛋白质合成。抑制延伸因子G（EF-G）的功能和EF-G与核糖体的分离。抗硫链菌素基因也常用作重组DNA/质粒技术的选择标记。
