CC   -!- FUNCTION: Involved in the regulation of different processes depending
CC       on the cell density. Acts together with sigma-54 to repress, perhaps
CC       indirectly, some genes (By similarity). {ECO:0000250}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=BAC93959.1; Type=Erroneous initiation; Evidence={ECO:0000305};
