Abstract

Proteins of free and polysome-derived ribosomal subunits of Bacillus licheniformis were fractionated by means of two-dimensional polyacrylamide gel electrophoresis. The free and derived 30S subunits have twelve protein components in common. Five proteins are present on the free 30S subunits only, whereas four proteins are exclusively found on the derived 30S subunits. The free and derived 50S subunits have at least twenty-eight proteins in common. Four proteins are unique for the derived and one for the free 50S subunits.

摘要

通过二维聚丙烯酰胺凝胶电泳对芽孢杆菌licheniformis 的游离和多核糖体衍生核糖体亚基的蛋白质进行了分离。游离和衍生的 30S 亚基共有十二个蛋白质成分。有五个蛋白质仅存在于游离的 30S 亚基上，而有四个蛋白质则专门存在于衍生的 30S 亚基上。游离和衍生的 50S 亚基至少有二十八个蛋白质是共同的。四个蛋白质是衍生的，一个是游离的 50S 亚基所特有的。
