CC   -!- FUNCTION: Involved in the temperature-dependent positive control of
CC       flagellum-driven swimming motility and cellular aggregation. Regulates
CC       fliC expression by directly interacting with fliC promoter (By
CC       similarity). {ECO:0000250}.
CC   -!- CAUTION: Originally described as slyA, but then it was found that two
CC       distinct genes had been named slyA. This gene was renamed hosA.
CC       {ECO:0000305}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=AAG57847.1; Type=Erroneous initiation; Evidence={ECO:0000305};
