Rhodobacter sphaeroides is able to assemble two different flagella, the subpolar flagellum (Fla1) and the polar flagella (Fla2). In this work, we report the swimming behavior of R. sphaeroides Fla2(+) cells lacking each of the proteins encoded by chemotactic operon 1. A model proposing how these proteins control Fla2 rotation is presented.
球形红杆菌能够组装两种不同的鞭毛,即亚极鞭毛(Fla1)和极鞭毛(Fla2)。在这项工作中,我们报告了缺乏趋化作用操纵子 1 编码的每种蛋白质的 R. sphaeroides Fla2(+)细胞的游动行为。提出了一个模型,说明这些蛋白质如何控制 Fla2 的旋转。
