FIG 5.

Flagellar motor inhibits PGA synthesis. Cartoon model of the B. subtilis flagellum with the location of relevant proteins indicated as matching colored text and symbols. Peptidoglycan is indicated in light gray, membrane is indicated in dark gray, the flagellar basal body is colored purple, and the flagellar hook is colored light blue. Genetic formalisms indicate the regulatory relationships of proteins mentioned in the text. Arrows indicate activation/promotion; T bars indicate repression/inhibition. Solid lines indicate empirical support for regulation, and dashed lines support by inference where the mechanism of regulation is unknown.
