Borrelia burgdorferi B31 cells lacking all linear plasmids or all but the 49-kb linear plasmid expressed the otherwise silent gene for the outer membrane protein OspC. In the first demonstration of a function for a circular plasmid of Borrelia spp., ospC was located on a 27-kb circular plasmid of B31.
缺乏所有线性质粒或除49 kb线性质粒外所有线性质粒的伯氏疏螺旋体B31细胞表达了原本沉默的外膜蛋白OspC基因。在首次证明伯氏疏螺旋体环形质粒的功能时,ospC位于B31的一个27 kb环形质粒上。
