CC   -!- FUNCTION: Member of the two-component regulatory system ArcB/ArcA.
CC       Represses a wide variety of aerobic enzymes under anaerobic conditions.
CC       It also may be involved in the osmoregulation of envelope proteins.
CC       When activated by ArcB, it negatively regulates the expression of genes
CC       of aerobic function. Activates the transcription of the plfB operon by
CC       binding to its promoter (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC   -!- PTM: Phosphorylated by ArcB. {ECO:0000250}.
CC   -!- CAUTION: There are two genes termed arcA in strain O6 of E.coli, one
CC       refers to an arginine deiminase and the other to a two-component
CC       regulator. {ECO:0000305}.
