Two large cryptic plasmids (59.2 and 65.9 kb) from isolates of Sulfobacillus thermotolerans from Yellowstone National Park (United States) and the Caribbean island of Montserrat were isolated and sequenced. This analysis revealed a common "backbone" region coding for a potential plasmid stability system plus a nonpheromone conjugation system containing homologues of both type IV and type II (tight adherence, or Tad-like) secretion systems.
两段来自美国黄石国家公园和蒙特塞拉特岛的嗜热硫杆菌分离株的大型隐秘质粒(59.2 和 65.9 kb)被分离并测序。该分析揭示了一个共同的“骨架”区域,编码潜在的质粒稳定系统,以及一个非信息素共轭系统,包含 IV 型和 II 型(紧密附着,或 Tad 样)分泌系统的同源物。
