CC   -!- FUNCTION: Functions in complex with FlhC as a master transcriptional
CC       regulator that regulates transcription of several flagellar and non-
CC       flagellar operons by binding to their promoter region. Activates
CC       expression of class 2 flagellar genes, including fliA, which is a
CC       flagellum-specific sigma factor that turns on the class 3 genes. Also
CC       regulates genes whose products function in a variety of physiological
CC       pathways. {ECO:0000255|HAMAP-Rule:MF_00725}.
CC   -!- SUBUNIT: Homodimer; disulfide-linked. Forms a heterohexamer composed of
CC       two FlhC and four FlhD subunits. Each FlhC binds a FlhD dimer, forming
CC       a heterotrimer, and a hexamer assembles by dimerization of two
CC       heterotrimers. {ECO:0000255|HAMAP-Rule:MF_00725}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00725}.
CC   -!- DOMAIN: The C-terminal region contains a putative helix-turn-helix
CC       (HTH) motif, suggesting that this region may bind DNA.
CC       {ECO:0000255|HAMAP-Rule:MF_00725}.
CC   -!- SIMILARITY: Belongs to the FlhD family. {ECO:0000255|HAMAP-
CC       Rule:MF_00725}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=CAP42437.1; Type=Erroneous initiation; Note=Extended N-terminus.; Evidence={ECO:0000305};
