CC -!- FUNCTION: Acts as a flagellar brake, regulating swimming and swarming
CC in a bis-(3'-5') cyclic diguanylic acid (c-di-GMP)-dependent manner.
CC Overexpression of this gene decreases swimming and swarming motility;
CC those cells that are motile turn predominantly counterclockwise. The D-
CC 118 mutant is still able to bind FliM but no longer affects motility
CC upon overexpression. Binds 1 c-di-GMP dimer per subunit.
CC {ECO:0000269|PubMed:16920715}.
CC -!- SUBUNIT: Monomer. Interacts with the flagellar basal bodies (By
CC similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Bacterial flagellum basal body
CC {ECO:0000269|PubMed:20346719}. Note=Localization lost in FliM mutants
CC E-155 or E-160.
CC -!- DOMAIN: The N-terminal domain is involved in FliG binding, the C-
CC terminal domain is involved in FliM binding.
CC -!- DISRUPTION PHENOTYPE: No visible motility phenotype. Disruption of this
CC gene suppresses the reduced motility of a yhjH disruption, thus the
CC double knockout is motile. Overexpression of this gene in a yhjH
CC disruption has the converse effect, i.e. it reduces motility further.
CC {ECO:0000269|PubMed:16920715, ECO:0000269|PubMed:20346719}.
CC -!- SIMILARITY: Belongs to the YcgR family. {ECO:0000305}.
