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:
phoBResponse regulator in two-component regulatory system with PhoR; This protein is a positive regulator for the phosphate regulon. Transcription of this operon is positively regulated by PhoB and PhoR when phosphate is limited. (229 aa)
phoRSensory histidine kinase in two-component regulatory system with PhoB; Member of the two-component regulatory system PhoR/PhoB involved in the phosphate regulon genes expression. PhoR may function as a membrane-associated protein kinase that phosphorylates PhoB in response to environmental signals. (431 aa)
nagEN-acetyl glucosamine specific PTS enzyme IIC, IIB, and IIA components; The phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS), a major carbohydrate active transport system, catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane. This system is involved in N-acetylglucosamine transport. It can also transport and phosphorylate the antibiotic streptozotocin. Could play a significant role in the recycling of peptidoglycan. (648 aa)
bssRRepressor of biofilm formation by indole transport regulation; Represses biofilm formation in M9C glu and LB glu media but not in M9C and LB media. Seems to act as a global regulator of several genes involved in catabolite repression and stress response and regulation of the uptake and export of signaling pathways. Could be involved the regulation of indole as well as uptake and export of AI-2 through a cAMP-dependent pathway. (127 aa)
phoQSensory histidine kinase in two-component regulatory system with PhoP; Member of the two-component regulatory system PhoP/PhoQ involved in adaptation to low Mg(2+) environments and the control of acid resistance genes. In low periplasmic Mg(2+), PhoQ functions as a membrane-associated protein kinase that undergoes autophosphorylation and subsequently transfers the phosphate to PhoP, resulting in the expression of PhoP-activated genes (PAG) and repression of PhoP- repressed genes (PRG). In high periplasmic Mg(2+), acts as a protein phosphatase that dephosphorylates phospho-PhoP, resulti [...] (486 aa)
phoPResponse regulator in two-component regulatory system with PhoQ; Member of the two-component regulatory system PhoP/PhoQ involved in adaptation to low Mg(2+) environments and the control of acid resistance genes. 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 repression of PAG and may lead to expression of some PRG (By similarity). Mediates magnesium influx to the cytosol by activation of MgtA. Pro [...] (223 aa)
lsrKAutoinducer-2 kinase; Catalyzes the phosphorylation of autoinducer-2 (AI-2) to phospho-AI-2, which subsequently inactivates the transcriptional regulator LsrR and leads to the transcription of the lsr operon. Phosphorylates the ring-open form of (S)-4,5-dihydroxypentane-2,3-dione (DPD), which is the precursor to all AI-2 signaling molecules, at the C5 position. Required for the regulation of the lsr operon and many other genes. (530 aa)
tqsAPheromone AI-2 transporter; Controls the transport of the quorum-sensing signal AI-2 either by enhancing its secretion or inhibiting its uptake and consequently represses biofilm formation and motility and affects the global gene expression in biofilms. (344 aa)
mliCInhibitor of c-type lysozyme, membrane-bound; Specifically inhibits C-type lysozymes. Belongs to the MliC family. Type 1 subfamily. (109 aa)
rcsDPhosphotransfer intermediate protein in two-component regulatory system with RcsBC; Component of the Rcs signaling system, which controls transcription of numerous genes. RcsD is a phosphotransfer intermediate between the sensor kinase RcsC and the response regulator RcsB. It acquires a phosphoryl group from RcsC and transfers it to RcsB. The system controls expression of genes involved in colanic acid capsule synthesis, biofilm formation and cell division. (890 aa)
rcsBResponse regulator in two-component regulatory system with RcsC and YojN; 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. The system regulates expression of numerous genes, including genes involved in colanic acid capsule synthesis, biofilm formation, cell division and outer membrane proteins synthesis. Also involved, with GadE, in control of glutamate-dependent acid resistance, and, with BglJ, in derepression of [...] (216 aa)
rcsCHybrid sensory kinase in two-component regulatory system with RcsB and YojN; Component of the Rcs signaling system, which controls transcription of numerous genes. RcsC functions as a membrane- associated protein kinase that phosphorylates RcsD in response to environmental signals. The phosphoryl group is then transferred to the response regulator RcsB. RcsC has also phosphatase activity. The system controls expression of genes involved in colanic acid capsule synthesis, biofilm formation and cell division. (949 aa)
srlQD-arabinose 5-phosphate isomerase; Catalyzes the reversible aldol-ketol isomerization between D- ribulose 5-phosphate (Ru5P) and D-arabinose 5-phosphate (A5P). It appears that the physiological function of G-API may be to synthesize the regulatory molecule A5P, which in turn participates in the induction of the gut operon through an unknown mechanism. It is also able of sustaining the biosynthetic pathway of 3-deoxy-D-manno- octulosonate (KDO), a unique 8-carbon sugar component of lipopolysaccharides (LPSs); Belongs to the SIS family. GutQ/KpsF subfamily. (321 aa)
rpoSRNA polymerase, sigma S (sigma 38) factor; 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. Controls, positively or negatively, the expression of several hundred genes, which are mainly involved in metabolism, transport, regulation and stress management. (330 aa)
malPMaltodextrin phosphorylase; Phosphorylase is an important allosteric enzyme in carbohydrate metabolism. Enzymes from different sources differ in their regulatory mechanisms and in their natural substrates. However, all known phosphorylases share catalytic and structural properties. (797 aa)
basSSensory histidine kinase in two-component regulatory system with BasR; Member of the two-component regulatory system BasS/BasR Autophosphorylates and activates BasR by phosphorylation. (363 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 (By similarity). (222 aa)
