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

Name: Work Video:
Duration: 3 min 30 s
Description: ABSTRACT 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.
