Bacillus licheniformis was transformed with plasmids pUB110 and pJJ10 (pUB110 - pBR322) isolated from Bac. subtilis and Escherichia coli, respectively. It was revealed that the structure and genetic properties of the plasmids did not change during the transformation process. pJJ101 (pJJ10-rib) DNA isolated from E. coli and containing helper pJJ10 plasmid was used, as a recipient. It was shown that pJJ101 rib markers were "rescued" by the resident plasmid during transformation of Bac. licheniformis (pJJ10). Plasmid pLP1 containing ribB, ribD, Kmr genes and the pUB110 replicator, was isolated from the transformants. pLP1 plasmid might be considered as a detected derivative of the parental pJJ101 plasmid. The deletion is presented by 3,9 MD segment that contains the pBR322 replicator. pLP1 DNA is capable of transforming plasmidless strains of Bac. licheniformis and Bac. subtilis.
地衣芽孢杆菌用分别从枯草芽孢杆菌和大肠杆菌中分离得到的质粒pUB110和pJJ10(pUB110 - pBR322)进行转化。结果表明,在转化过程中质粒的结构和遗传特性未发生改变。从大肠杆菌中分离得到的、含有辅助质粒pJJ10的pJJ101(pJJ10 - rib)DNA用作受体。结果显示,在地衣芽孢杆菌(pJJ10)转化过程中,pJJ101 rib标记被常驻质粒“拯救”。从转化子中分离出含有ribB、ribD、Kmr基因和pUB110复制子的质粒pLP1。pLP1质粒可被视为亲本pJJ101质粒的检测衍生物。缺失部分由包含pBR322复制子的3.9 MD片段呈现。pLP1 DNA能够转化无质粒的地衣芽孢杆菌和枯草芽孢杆菌菌株。
