CC -!- FUNCTION: Member of the two-component regulatory system HssS/HssR
CC involved in intracellular heme homeostasis and tempering of
CC staphylococcal virulence. HssS functions as a heme sensor histidine
CC kinase which is autophosphorylated at a histidine residue and transfers
CC its phosphate group to an aspartate residue of HssR. HssR/HssS
CC activates the expression of hrtAB, an efflux pump, in response to
CC extracellular heme, hemin, hemoglobin or blood.
CC {ECO:0000256|ARBA:ARBA00037219}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + protein L-histidine = ADP + protein N-phospho-L-
CC histidine.; EC=2.7.13.3; Evidence={ECO:0000256|ARBA:ARBA00000085};
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
CC {ECO:0000313|EMBL:EEG91968.1}.
