Abstract

Regulatory gene in Penicillin G Acylase operon (pacR) of E. coli D816 was located in a Taq1-Dra1 fragment within the pac structure gene. Two ORFs were found in this fragment and their transcriptional orientations were opposite with pac. ORF2 was determined as pacR by point mutation.

大肠杆菌D816青霉素G酰化酶操纵子调控基因的定位
大肠杆菌D816青霉素G酰化酶操纵子(pacR)的调控基因位于pacR结构基因的Taq1-Dra1片段上。在该片段中发现了两个orf,它们的转录方向与pac相反,通过点突变确定ORF2为pacR。
