Abstract

We have cloned and sequenced some prlA mutant alleles of the Escherichia coli secY gene. From the mutation sites determined, it is strongly suggested that distinct regions in the SecY (PrlA) protein are involved in the recognition of different structural features of a signal peptide as it functions.

摘要

我们已经克隆并测序了大肠杆菌secY基因的一些prlA突变等位基因。根据所确定的突变位点,强烈表明SecY(PrlA)蛋白中的不同区域在信号肽发挥功能时参与识别其不同的结构特征。
