RNA polymerase sigma factor for flagellar regulon FliA; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor controls the expression of flagella-related genes; Belongs to the sigma-70 factor family. FliA subfamily.

Chemotaxis protein CheA.

Polar flagellar FlgN.

Chemotaxis response regulator protein-glutamate methylesterase; Involved in chemotaxis. Part of a chemotaxis signal transduction system that modulates chemotaxis in response to various stimuli. Catalyzes the demethylation of specific methylglutamate residues introduced into the chemoreceptors (methyl-accepting chemotaxis proteins or MCP) by CheR. Also mediates the irreversible deamidation of specific glutamine residues to glutamic acid. Belongs to the CheB family.

cheW-like protein.

Polar flagellar protein FliS (polar flagellar protein FlaJ).

Chemotaxis protein CheW.

Polar flagellar hook-associated protein 2 (HAP2) (flagellar cap protein); Required for morphogenesis and for the elongation of the flagellar filament by facilitating polymerization of the flagellin monomers at the tip of growing filament. Forms a capping structure, which prevents flagellin subunits (transported through the central channel of the flagellum) from leaking out without polymerization at the distal end.
