Abstract
Megacins A-216 and A-19213 in Bacillus megaterium are plasmid encoded, as shown by analysis of cured, non-megacinogenic (Meg-) derivatives of strains 216 and ATCC 19213 and by polyethylene glycol-mediated protoplast transformation of Meg- bacteria with plasmid DNA. The results of both techniques implicated a 31-megadalton plasmid, pBM309, in megacin A-216 production and a 29-megadalton plasmid, pBM113, in megacin A-19213 production.
摘要
巨大芽孢杆菌中的巨杀菌素A - 216和A - 19213由质粒编码，这是通过对菌株216和ATCC 19213的治愈型、无巨杀菌素生成能力（Meg-）的衍生物进行分析，以及通过用质粒DNA对Meg-细菌进行聚乙二醇介导的原生质体转化而表明的。这两种技术的结果表明，一个31兆道尔顿的质粒pBM309参与巨杀菌素A - 216的产生，一个29兆道尔顿的质粒pBM113参与巨杀菌素A - 19213的产生。
