Abstract

The 2.4-kb plasmid pAP1 from Arcanobacterium (Actinomyces) pyogenes had sequence similarity within the putative replication protein and double-stranded origin with the pIJ101/pJV1 family of plasmids. pJGS84, a derivative of pAP1 containing a kanamycin resistance gene, was able to replicate in Escherichia coli and Corynebacterium pseudotuberculosis, as well as in A. pyogenes. Detection of single-stranded DNA intermediates of pJGS84 replication suggested that this plasmid replicates by the rolling circle mechanism.

摘要

来自化脓隐秘杆菌(放线菌属)的2.4kb质粒pAP1在假定的复制蛋白和双链原点区域与pIJ101/pJV1质粒家族具有序列相似性。pJGS84是pAP1的衍生物,含有卡那霉素抗性基因,能够在大肠杆菌、伪结核棒状杆菌以及化脓隐秘杆菌中复制。对pJGS84复制过程中单链DNA中间体的检测表明,该质粒通过滚环机制进行复制。
