CC   -!- FUNCTION: Member of the two-component regulatory system HssS/HssR
CC       involved in intracellular heme homeostasis and tempering of
CC       staphylococcal virulence. Phosphorylated HssR binds to a direct repeat
CC       sequence within hrtAB promoter and activates the expression of hrtAB,
CC       an efflux pump, in response to extracellular heme, hemin, hemoglobin or
CC       blood (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000305}.
CC   -!- PTM: Phosphorylated by HssS. {ECO:0000250}.
