Abstract

The 40S ribonucleoprotein particle in Escherichia coli cells, accumulated in the presence of a low concentration of chloramphenicol, lacks at least four ribosomal structural protein components which are present in the mature 50S ribosomal subunit. The 40S ribonucleoprotein prepared by exposing the 50S ribosomal subunit to a concentrated lithium chloride solution may also be deficient in the same protein components.

摘要

在低浓度氯霉素存在的情况下积累的大肠杆菌细胞中的40S核糖核蛋白颗粒，至少缺少成熟50S核糖体亚基中存在的四种核糖体结构蛋白成分。通过将50S核糖体亚基暴露于浓氯化锂溶液中制备的40S核糖核蛋白在相同的蛋白质成分上也可能存在缺陷。
