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

araCTranscriptional regulator (AraC/XylS family) for ara operon; Transcription factor that regulates the expression of several genes involved in the transport and metabolism of L-arabinose. (281 aa)
acrBSimilar to E. coli acridine efflux pump (AAC73564.1); Blastp hit to AAC73564.1 (1049 aa), 94% identity in aa 1 - 1048. (1049 aa)
acrASimilar to E. coli acridine efflux pump (AAC73565.1); Blastp hit to AAC73565.1 (397 aa), 91% identity in aa 1 - 397; Belongs to the membrane fusion protein (MFP) (TC 8.A.1) family. (397 aa)
purRTranscriptional repressor for pur regulon, glyA, glnB, prsA, speA (GalR/LacI family); Is the main repressor of the genes involved in the de novo synthesis of purine nucleotides, regulating purB, purC, purEK, purF, purHD, purL, purMN and guaBA expression. PurR is allosterically activated to bind its cognate DNA by binding the purine corepressors, hypoxanthine or guanine, thereby effecting transcription repression. (341 aa)
marAAraC/XylS family transcriptional activator of defense systems; May be a transcriptional activator of genes involved in the multiple antibiotic resistance (Mar) phenotype. It can also activate genes such as sodA, zwf and micF. (144 aa)
marRTranscriptional repressor of marRAB operon; Repressor of the marRAB operon which is involved in the activation of both antibiotic resistance and oxidative stress genes. Binds to the marO operator/promoter site. (144 aa)
marCPutative MarC Transporter; Multiple antibiotic resistance protein MARC. (SW:MARC_SALTY). (221 aa)
gyrADNA gyrase, subunit A; A type II topoisomerase that negatively supercoils closed circular double-stranded (ds) DNA in an ATP-dependent manner to modulate DNA topology and maintain chromosomes in an underwound state, and also catalyzes the interconversion of other topological isomers of double-stranded DNA rings, including catenanes and knotted rings. Replenishes negative supercoiling downstream of highly transcribed genes to help control overall chromosomal supercoiling density. E.coli makes 15% more negative supercoils in pBR322 plasmid DNA than S.typhimurium; the S.typhimurium GyrB s [...] (878 aa)
pgtAActivator protein; Member of the two-component regulatory system PgtB/PgtA that regulates the inducible phosphoglycerate transport system. When activated by PgtB it acts in conjunction with sigma-54 as a transcriptional activator. (415 aa)
parCDNA topoisomerase IV, subunit A; Topoisomerase IV is essential for chromosome segregation. It relaxes supercoiled DNA. Performs the decatenation events required during the replication of a circular DNA molecule. Belongs to the type II topoisomerase GyrA/ParC subunit family. ParC type 1 subfamily. (752 aa)
parEDNA topoisomerase IV, subunit B; Topoisomerase IV is essential for chromosome segregation. It relaxes supercoiled DNA. Performs the decatenation events required during the replication of a circular DNA molecule. Belongs to the type II topoisomerase family. ParE type 1 subfamily. (630 aa)
tolCOuter membrane channel; Specific tolerance to colicin E1; segregation of daughter chromosomes; role in organic solvent tolerance; similar to E. coli outer membrane channel; specific tolerance to colicin E1; segregation of daughter chromosomes (AAC76071.1); Blastp hit to AAC76071.1 (495 aa), 89% identity in aa 1 - 495. (491 aa)
acrESimilar to E. coli transmembrane protein affects septum formation and cell membrane permeability (AAC76297.1); Blastp hit to AAC76297.1 (385 aa), 88% identity in aa 1 - 380; Belongs to the membrane fusion protein (MFP) (TC 8.A.1) family. (385 aa)
acrFRND family multidrug transport protein; Similar to E. coli integral transmembrane protein; acridine resistance (AAC76298.1); Blastp hit to AAC76298.1 (1034 aa), 22% identity in aa 1 - 506; acriflavin resistance protein F. (1037 aa)
gyrBDNA gyrase, subunit B; A type II topoisomerase that negatively supercoils closed circular double-stranded (ds) DNA in an ATP-dependent manner to modulate DNA topology and maintain chromosomes in an underwound state, and also catalyzes the interconversion of other topological isomers of double-stranded DNA rings, including catenanes and knotted rings. Replenishes negative supercoiling downstream of highly transcribed genes to help control overall chromosomal supercoiling density. E.coli makes 15% more negative supercoils in pBR322 plasmid DNA than S.typhimurium; the S.typhimurium GyrB s [...] (804 aa)
soxSTranscriptional activator of superoxide response regulon; Transcriptional activator of the superoxide response regulon of E.coli that includes at least 10 genes such as sodA, nfo, zwf and micF. Binds the DNA sequence 5'-GCACN(7)CAA-3'. It also facilitates the subsequent binding of RNA polymerase to the micF and the nfo promoters (By similarity). (107 aa)
soxRRedox-sensing transcriptional activator SoxR; Activates the transcription of the soxS gene which itself controls the superoxide response regulon. SoxR contains a 2Fe-2S iron- sulfur cluster that may act as a redox sensor system that recognizes superoxide. The variable redox state of the Fe-S cluster is employed in vivo to modulate the transcriptional activity of SoxR in response to specific types of oxidative stress (By similarity). (152 aa)
