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

walKSensory box histidine kinase VicK, putative; Member of the two-component regulatory system WalK/WalR that regulates genes involved in cell wall metabolism, virulence regulation, biofilm production, oxidative stress resistance and antibiotic resistance via direct or indirect regulation of autolysins. Functions as a sensor protein kinase which is autophosphorylated at a histidine residue in the dimerization domain and transfers its phosphate group to the conserved aspartic acid residue in the regulatory domain of WalR. In turn, WalR binds to the upstream promoter regions of the target ge [...] (608 aa)

walR
Two-component response regulator, putative; Member of the two-component regulatory system WalK/WalR that regulates genes involved in cell wall metabolism, virulence regulation, biofilm production, oxidative stress resistance and antibiotic resistance via direct or indirect regulation of autolysins. Functions as a transcription regulator by direct binding to promoter regions. Positively controls the cell wall-hydrolytic activity through regulation of atlA and lytM, as well as induces transcription of isaA, sceD, ssaA, and four ssaA- related genes. Binds directly to the lytM, ssaA and is [...]

arlR
DNA-binding response regulator, putative; Member of the two-component regulatory system ArlS/ArlR involved in the regulation of adhesion, autolysis, multidrug resistance and virulence. 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 (serine protease), spa (surface protein A) and hla (alpha-hemolysin). Could inhibit biofilm development by a mechanism independent of the [...]

srrA
DNA-binding response regulator, putative; Member of the two-component regulatory system SrrA/SrrB, which is involved in the global regulation of staphylococcal virulence factors in response to environmental oxygen levels as well as biofilm formation. Plays also an essential role in host-derived nitric oxide resistance by regulating hmp/flavohemoglobin, an enzyme that detoxifies nitric oxide by converting it to nitrate (By similarity). Functions as a transcription regulator by direct binding to promoter regions of target genes (By similarity).

saeR
Response regulator, putative; Member of the two-component regulatory system SaeR/SaeS involved in the regulation of staphylococcal virulence factors in a strain-dependent fashion. Probably functions as a transcriptional regulator via a specific DNA-binding domain, recognizing motifs near the promoter sequences of target genes. SaeR/SaeS activates the expression of exoproteins involved in adhesion and invasion of host cells, including hemolysins (Hla, Hlb), Coa, DNase, Spa and cell wall- associated proteins (Emp, Eap, FnbA). Acts probably downstream of the Agr system in the regulatory c [...]

graR
Conserved hypothetical protein; Member of the two-component regulatory system GraR/GraS involved in resistance against cationic antimicrobial peptides (CAMPs). Upon phosphorylation by GraS, functions as a transcription regulator by direct binding to promoter regions of target genes such as adhesins, exoproteins, transporters, toxins, and proteins involved in cell wall synthesis. Down-regulates the expression of many genes involved in RNA and amino acid synthesis or glycolysis.

mprF
Conserved hypothetical protein; Catalyzes the transfer of a lysyl group from L-lysyl- tRNA(Lys) to membrane-bound phosphatidylglycerol (PG), which produces lysylphosphatidylglycerol (LPG), a major component of the bacterial membrane with a positive net charge. LPG synthesis contributes to bacterial virulence as it is involved in the resistance mechanism against cationic antimicrobial peptides (CAMP) produces by the host's immune system (defensins, cathelicidins) and by the competing microorganisms (bacteriocins). In fact, the modification of anionic phosphatidylglycerol with positively [...]
