CC   -!- FUNCTION: Member of the two-component regulatory system SrrA/SrrB,
CC       which is involved in the global regulation of staphylococcal virulence
CC       factors in response to environmental oxygen levels as well as biofilm
CC       formation. Also plays an essential role in host-derived nitric oxide
CC       resistance by regulating hmp/flavohemoglobin, an enzyme that detoxifies
CC       nitric oxide by converting it to nitrate (By similarity). Functions as
CC       a transcription regulator by direct binding to promoter regions of
CC       target genes (By similarity). {ECO:0000250|UniProtKB:Q5HFT0,
CC       ECO:0000250|UniProtKB:Q9L524}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC   -!- PTM: Phosphorylated by SrrB. {ECO:0000250}.
