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:
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)
rcsBLuxR/UhpA family response regulator in two-component regulatory system with RcsC; Component of the Rcs signaling system, which controls transcription of numerous genes. RcsB is the response regulator that binds to regulatory DNA regions. Can function both in an RcsA-dependent or RcsA-independent manner. (216 aa)
yegDSimilar to E. coli putative heat shock protein (AAC75130.1); Blastp hit to AAC75130.1 (471 aa), 88% identity in aa 22 - 471. (450 aa)
phsAHydrogen sulfide production membrane anchoring protein; Component of the PhsABC thiosulfate reductase that catalyzes the reduction of thiosulfate to sulfite and hydrogen sulfide, with menaquinol as the sole electron donor. Proton motive force (PMF) is required to drive transmembrane electron transfer within the reductase. The PhsA subunit contains the active site molybdenum-bis(molybdopterin guanine dinucleotide) (Mo-bis-MGD) cofactor. (758 aa)
pagOPredicted integral membrane protein; PAGO protein. (SW:PAGO_SALTY). (304 aa)
nifJSimilar to E. coli putative oxidoreductase, Fe-S subunit (AAC74460.1); Blastp hit to AAC74460.1 (1174 aa), 92% identity in aa 1 - 1174. (1174 aa)
osmXPutative periplasmic component; Part of the OsmU ABC transporter complex, which is involved in the uptake of osmoprotectants such as choline-O-sulfate and glycine betaine. (300 aa)
ssaUSecretion system apparatus protein; Part of a type III secretion system; Belongs to the type III secretion exporter family. (352 aa)
ssaKSecretion system apparatus protein SSAK. (SW:SSAK_SALTY). (224 aa)
yadISimilar to E. coli putative PTS enzyme II B component (AAC73240.1); Blastp hit to AAC73240.1 (146 aa), 76% identity in aa 1 - 146. (146 aa)
yjeSPutative Fe-S protein; Catalyzes the conversion of epoxyqueuosine (oQ) to queuosine (Q), which is a hypermodified base found in the wobble positions of tRNA(Asp), tRNA(Asn), tRNA(His) and tRNA(Tyr); Belongs to the QueG family. (384 aa)
basRResponse regulator in two-component regulatory system with BasS; Member of the two-component regulatory system BasS/BasR. BasR induces the transcription of the ugd, ais, arnBCADTEF and eptA-basRS loci, all involved in resistance to polymyxin. Represses the transcription of pmrD. Plays a role in the adaptation of the organism to the host environment, in particular to neutrophils, and therefore it plays a role in virulence as well. (222 aa)
yhjQPutative ATPase involved in chromosome partitioning; Essential for cellulose biosynthesis. May play a role in subcellular localization of an active cellulose biosynthesis apparatus at the bacterial cell pole (By similarity); Belongs to the BcsQ family. (250 aa)
STM3117Putative lactoylglutathione lyase; Is critically involved in promoting the replication of S.typhimurium cells inside host macrophages, suggesting a role in the establishment of bacterial colonization within macrophages. May be involved in the biosynthesis and modification of the peptidoglycan layer of the cell wall. (144 aa)
ygbOPutative hydrogenase subunit; Responsible for synthesis of pseudouridine from uracil-13 in transfer RNAs; Belongs to the pseudouridine synthase TruD family. (349 aa)
invAInvasion protein; Involved in the invasion of the cells of the intestinal epithelium. Could be involved in the translocation of the InvE protein; Belongs to the FHIPEP (flagella/HR/invasion proteins export pore) family. (685 aa)
hycEPart of FHL complex; similar to E. coli large subunit of hydrogenase 3 (part of FHL complex) (AAC75763.1); Blastp hit to AAC75763.1 (569 aa), 97% identity in aa 1 - 569. (569 aa)
