Abstract

By using a reconstituted cell-free system we have demonstrated the existence of a soluble activity that is required for the export of proteins in Escherichia coli. This export factor sediments at about 12 S. It has been partially purified by passage through an omega-NH2-butylagarose column and by salt elution off a DEAE matrix. The export factor does not contain 6S RNA.

摘要

通过使用重组的无细胞系统,我们证明了大肠杆菌中蛋白质输出所需的一种可溶性活性的存在。这种输出因子沉降系数约为12S。它已通过ω-NH2-丁基琼脂糖柱和从DEAE基质上进行盐洗脱进行了部分纯化。该输出因子不含6S RNA。
