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}.
