Protein
HTH-type transcriptional regulator ArcR
Organism
Staphylococcus aureus (strain NCTC 8325)
Function
Positively regulates the expression of the arcABDCR operon under anaerobic conditions, by binding to the consensus motif 5'-TGTGAN(6)TCACA-3', thus playing an essential role in arginine catabolism. May also control the expression of genes encoding proteins which are involved in anaerobic metabolism. Can bind cyclic AMP.
