Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
a 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding to each other.

hssSSensor histidine kinase; Member of the two-component regulatory system HssS/HssR involved in intracellular heme homeostasis and tempering of staphylococcal virulence. HssS functions as a heme sensor histidine kinase which is autophosphorylated at a histidine residue and transfers its phosphate group to an aspartate residue of HssR. HssR/HssS activates the expression of HrtAB, an efflux pump, in response to extracellular heme, hemin, hemoglobin or blood (By similarity). (451 aa)    
Predicted Functional Partners:
hssR
DNA-binding response regulator; Member of the two-component regulatory system HssS/HssR involved in intracellular heme homeostasis and tempering of staphylococcal virulence. Phosphorylated HssR binds to a direct repeat sequence within hrtAB promoter and activates the expression of hrtAB, an efflux pump, in response to extracellular heme, hemin, hemoglobin or blood (By similarity).
 
 
 0.996
hrtB
ABC transporter, permease protein; Part of the ABC transporter complex hrt involved in hemin import. Responsible for the translocation of the substrate across the membrane (By similarity).
 
 
 
 0.931
saeR
DNA-binding response regulator SaeR; Member of the two-component regulatory system SaeR/SaeS. Probably functions as a transcriptional regulator via a specific DNA- binding domain, recognizing motifs near the promoter sequences of target genes (By similarity).
 
 
 0.910
hrtA
ABC transporter, ATP-binding protein; Part of the ABC transporter complex hrt involved in hemin import. Responsible for energy coupling to the transport system (By similarity).
 
 
 0.905
arlR
DNA-binding response regulator ArlR; Member of the two-component regulatory system ArlS/ArlR.
 
 
 0.900
