In Rhodobacter sphaeroides Chemotactic Operon 1 Regulates Rotation of the Flagellar System 2

摘要

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.
