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:
yacAPutative inner membrane protein; Regulates secA expression by translational coupling of the secM secA operon. Translational pausing at a specific Pro residue 5 residues before the end of the protein may allow disruption of a mRNA repressor helix that normally suppresses secA translation initiation. Belongs to the SecM family. (142 aa)
secAPreprotein translocase; Part of the Sec protein translocase complex. Interacts with the SecYEG preprotein conducting channel. Has a central role in coupling the hydrolysis of ATP to the transfer of proteins into and across the cell membrane, serving both as a receptor for the preprotein-SecB complex and as an ATP-driven molecular motor driving the stepwise translocation of polypeptide chains across the membrane. (901 aa)
yaiBPutative cytoplasmic protein; Inhibits RpoS proteolysis by regulating RssB activity, thereby increasing the stability of the sigma stress factor RpoS especially during phosphate and magnesium starvation, but also in stationary phase and during nitrogen starvation. Its effect on RpoS stability is due to its interaction with RssB, which probably blocks the interaction of RssB with RpoS, and the consequent delivery of the RssB-RpoS complex to the ClpXP protein degradation pathway. Belongs to the IraP family. (88 aa)
clpPProteolytic subunit of clpA-clpP ATP-dependent serine protease; Cleaves peptides in various proteins in a process that requires ATP hydrolysis. Has a chymotrypsin-like activity. Plays a major role in the degradation of misfolded proteins. Belongs to the peptidase S14 family. (207 aa)
clpXSpecificity component of clpA-clpP ATP-dependent serine protease, chaperone; ATP-dependent specificity component of the Clp protease. It directs the protease to specific substrates. Can perform chaperone functions in the absence of ClpP. (423 aa)
ompFOuter membrane protein 1a (ia;b;f), porin; Forms pores that allow passive diffusion of small molecules across the outer membrane. It is also a receptor for the bacteriophage T2 (By similarity). (363 aa)
yljAPutative cytoplasmic protein; Involved in the modulation of the specificity of the ClpAP- mediated ATP-dependent protein degradation; Belongs to the ClpS family. (106 aa)
ompAPutative membrane component hydrogenase; With TolR probably plays a role in maintaining the position of the peptidoglycan cell wall in the periplasm. Acts as a porin with low permeability that allows slow penetration of small solutes; an internal gate slows down solute passage. (350 aa)
iraMPutative cytoplasmic protein; Involved in the stabilization of the sigma stress factor RpoS; Belongs to the IraM/RssC family. (120 aa)
phoPResponse regulator in two-component regulatory system with PhoQ; Member of the two-component regulatory system PhoP/PhoQ which regulates the expression of genes involved in virulence, adaptation to acidic and low Mg(2+) environments and resistance to host defense antimicrobial peptides. Essential for intramacrophage survival of S.typhimurium. In low periplasmic Mg(2+), PhoQ phosphorylates PhoP, resulting in the expression of PhoP-activated genes (PAG) and repression of PhoP-repressed genes (PRG). In high periplasmic Mg(2+), PhoQ dephosphorylates phospho-PhoP, resulting in the repressio [...] (224 aa)
pagCReduced macrophage survival protein; Essential for full virulence and survival within macrophages; Belongs to the outer membrane OOP (TC 1.B.6) superfamily. Ail family. (185 aa)
ssrASecretion system regulator: Sensor component; SpiR (gi|1498305). (920 aa)
hnrResponse regulator in protein turnover; Regulates the turnover of the sigma S factor (RpoS) by promoting its proteolysis in exponentially growing cells. Acts by binding and delivering RpoS to the ClpXP protease. RssB is not co- degraded with RpoS, but is released from the complex and can initiate a new cycle of RpoS recognition and degradation. (337 aa)
cysASulfate permease A protein; Part of the ABC transporter complex CysAWTP involved in sulfate/thiosulfate import. Responsible for energy coupling to the transport system. (365 aa)
STM2446Putative iron-dependent peroxidase; Similar to E. coli orf, hypothetical protein (AAC75484.1); Blastp hit to AAC75484.1 (308 aa), 94% identity in aa 10 - 308. (299 aa)
clpBATP-dependent protease; Part of a stress-induced multi-chaperone system, it is involved in the recovery of the cell from heat-induced damage, in cooperation with DnaK, DnaJ and GrpE. Acts before DnaK, in the processing of protein aggregates. Protein binding stimulates the ATPase activity; ATP hydrolysis unfolds the denatured protein aggregates, which probably helps expose new hydrophobic binding sites on the surface of ClpB-bound aggregates, contributing to the solubilization and refolding of denatured protein aggregates by DnaK (By similarity). Required for colonization of the gastroi [...] (857 aa)
rpoSSigma S (sigma 38) factor of RNA polymerase; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is the master transcriptional regulator of the stationary phase and the general stress response. (330 aa)
hflBATP-dependent zinc-metallo protease; Acts as a processive, ATP-dependent zinc metallopeptidase for both cytoplasmic and membrane proteins. Plays a role in the quality control of integral membrane proteins; In the central section; belongs to the AAA ATPase family. (644 aa)
rpoHSigma H factor of RNA polymerase; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is involved in regulation of expression of heat shock genes. (284 aa)
secBMolecular chaperone in protein export; One of the proteins required for the normal export of preproteins out of the cell cytoplasm. It is a molecular chaperone that binds to a subset of precursor proteins, maintaining them in a translocation-competent state. It also specifically binds to its receptor SecA; Belongs to the SecB family. (155 aa)
mgtBMg2+ transport protein; Mediates magnesium influx to the cytosol. Belongs to the cation transport ATPase (P-type) (TC 3.A.3) family. Type IIIB subfamily. (908 aa)
mgtCMg2+ transport protein; Virulence factor required for growth in low Mg(2+) medium and for intramacrophage survival. May be involved in regulating membrane potential by activating Na(+)/K(+)-ATPase. Belongs to the MgtC/SapB family. (231 aa)
atpBMembrane-bound ATP synthase, F0 sector, subunit a; Key component of the proton channel; it plays a direct role in the translocation of protons across the membrane. (271 aa)
yjaBPutative acetyltransferase; N-epsilon-lysine acetyltransferase that catalyzes acetylation of a large number of proteins; Belongs to the acetyltransferase family. (145 aa)
mopAChaperone Hsp60 with peptide-dependent ATPase activity; Prevents misfolding and promotes the refolding and proper assembly of unfolded polypeptides generated under stress conditions. (548 aa)
mgtAP-type ATPase; Mediates magnesium influx to the cytosol. (902 aa)
dnaKChaperone Hsp70; Acts as a chaperone. (638 aa)
