CC   -!- FUNCTION: Positively regulates the expression of the arcABDCR operon
CC       under anaerobic conditions, thus playing an essential role in arginine
CC       catabolism. May also control the expression of genes encoding proteins
CC       which are involved in anaerobic metabolism. Can bind cyclic AMP (By
CC       similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
