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
Your Input:
ompRTwo-component response regulator OmpR; Member of the two-component regulatory system EnvZ/OmpR involved in regulating expression of the outer membrane porins OmpC and OmpF as well as other genes. Unlike E.coli or S.typhimurium both porins are expressed constitutively. Involved in regulation of the biosynthesis of Vi polysaccharide, a capsular antigen thought to be involved in the virulence of S.typhi. Vi antigen is synthesized at low NaCl concentrations (under 0.4 M). Binds to the promoter of both ompC and ompF (By similarity). (239 aa)
STY0012DnaK protein (heat shock protein 70); Acts as a chaperone. (638 aa)
sigECell invasion protein; Molecular chaperone required for SopB/SigD stabilization and secretion; Belongs to the IpgE/SigE chaperone family. (113 aa)
sigDCell invasion protein; Converts phosphatidylinositol 3,4,5-trisphosphate (PtdIns 3,4,5-P3) to PtdIns 3-P and prevents the transition of PtdIns 3-P to PtdIns 3,5-P2. It is one of the known effectors injected by Salmonella into the host cell and is required for invasion and for an efficient generation and maintenance of Salmonella-containing vacuole (SVC). Alteration of the phosphoinositide composition of the plasma membrane causes membrane ruffling and actin cytoskeleton rearrangements. The persistence of PtdIns 3-P diverts the SCV from the endocytic pathway resulting in enlarged vesicl [...] (561 aa)
ssrAPutative two-component sensor kinase; Similar to Salmonella typhimurium SpiR TR:P74862 (EMBL:U51927) (823 aa) fasta scores: E(): 0, 98.1% id in 823 aa, and to Escherichia coli sensor protein TorS SW:TORS_ECOLI (P39453; P75887) (904 aa) fasta scores: E(): 1.3e-26, 27.8% id in 598 aa. (920 aa)
ssrBPutative two-component response regulator; Similar to Salmonella typhimurium SsrB TR:O54305 (EMBL:Z95891) (193 aa) fasta scores: E(): 0, 100.0% id in 193 aa, and to Streptococcus pneumoniae response regulator rr03 TR:Q9S1J7 (EMBL:AJ006393) (210 aa) fasta scores: E(): 1.4e-19, 34.5% id in 206 aa; Fasta hit to UHPA_ECOLI (196 aa), 33% identity in 202 aa overlap; Fasta hit to NARL_ECOLI (216 aa), 32% identity in 198 aa overlap; Paralogue of E. coli uvrY (UVRY_ECOLI); Fasta hit to UVRY_ECOLI (218 aa), 31% identity in 206 aa overlap. (212 aa)
STY2343Putative two-component system sensor kinase; Orthologue of E. coli baeS (BAES_ECOLI); Fasta hit to BAES_ECOLI (467 aa), 89% identity in 467 aa overlap. (467 aa)
STY2344Putative two-component system response regulator; Fasta hit to TORR_ECOLI (230 aa), 37% identity in 231 aa overlap; Fasta hit to YLCA_ECOLI (227 aa), 35% identity in 223 aa overlap; Fasta hit to RSTA_ECOLI (242 aa), 33% identity in 228 aa overlap; Fasta hit to YGIX_ECOLI (219 aa), 35% identity in 222 aa overlap; Fasta hit to OMPR_ECOLI (239 aa), 37% identity in 241 aa overlap; Fasta hit to ARCA_ECOLI (238 aa), 32% identity in 233 aa overlap; Fasta hit to CPXR_ECOLI (232 aa), 37% identity in 225 aa overlap; Fasta hit to PHOB_ECOLI (229 aa), 40% identity in 224 aa overlap; Fasta hit to P [...] (240 aa)
sicPChaperone (associated with virulence); Molecular chaperone required for SptP stabilization and secretion; Belongs to the SicP family. (116 aa)
spaTUnknown function; Type III secretion-associated chaperone required for SipB and SipC stabilization. Prevents premature association of SipB with SipC, which may lead to their targeting for degradation. Along with InvF, required for transcription activation of sigDE (sopB pipC), sicAsipBCDA, and sopE (By similarity). (165 aa)
STY3875Two-component system sensory histidine kinase; Member of the two-component regulatory system NtrB/NtrC, which controls expression of the nitrogen-regulated (ntr) genes in response to nitrogen limitation. Under conditions of nitrogen limitation, NtrB autophosphorylates and transfers the phosphoryl group to NtrC. In the presence of nitrogen, acts as a phosphatase that dephosphorylates and inactivates NtrC. (349 aa)
envZTwo-component sensor kinase EnvZ; Member of the two-component regulatory system EnvZ/OmpR involved in regulating expression of the outer membrane porins OmpC and OmpF as well as other genes. Unlike E.coli or S.typhimurium both porins are expressed constitutively. Involved in regulation of the biosynthesis of Vi polysaccharide, a capsular antigen thought to be involved in the virulence of S.typhi. Vi antigen is synthesized at low NaCl concentrations (under 0.4 M). EnvZ functions as a membrane-associated protein kinase that phosphorylates OmpR in response to environmental signals (By sim [...] (450 aa)
