STRINGSTRING
STRING protein interaction network
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.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

norGConserved hypothetical protein; Positively regulates the expression of the NorB efflux pump and negatively regulates the expression of the AbcA efflux pump. Binds specifically to the promoters of norA, norB and norC and abcA genes. Overexpression of norG leads to an increase in the level of resistance to quinolones, associated with a threefold increase in norB transcripts. Disruption of norG leads to an increase in the level of resistance to methicillin, cefotaxime, penicillin G, and nafcillin, associated with a threefold increase in abcA transcripts. Could also have an aminotransferas [...] (465 aa)

norB
Conserved hypothetical protein; Multidrug efflux pump that acts independently of NorA and is one of the factors that confers resistance against diverse quinolones and chemical compounds. Extrudes norfloxacin, ciprofloxacin, cetrimide, tetraphenylphosphonium ion (TPP), sparfloxacin, moxifloxacin and ethidium bromide. Contributes also to the efflux of tetracycline.

arlS
Conserved hypothetical protein; Member of the two-component regulatory system ArlS/ArlR involved in the regulation of adhesion, autolysis, multidrug resistance and virulence. ArlS probably functions as a sensor protein kinase which is autophosphorylated at a histidine residue and transfers its phosphate group to ArlR. ArlS/ArlR affects expression of the multidrug resistance transporter norA and interacts with both Agr (virulence accessory gene regulator) (negatively) and SarA (staphylococcal accessory regulator) (positively) to modulate several virulence factor genes, including ssp (se [...]

Conserved hypothetical protein.

mgrA
Conserved hypothetical protein; Regulatory protein involved in autolytic activity, multidrug resistance and virulence. Controls autolysis by inactivating LytM, LytN (autolysins) and SarV (autolysis activator) and activating ArlRS, LrgAB and LytSR (autolysis inhibitors). Acts as a dual regulator for resistance to multiple drugs by inactivating NorB and tet38 and activating NorA. Positively controls the expression of virulence accessory gene regulator (agr) to promote alpha-hemolysin (hla) transcription and down-regulates staphylococcal accessory regulator (sarS), leading to repression o [...]
