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

msbALipid ABC transporter permease/ATPase; Involved in lipid A export and possibly also in glycerophospholipid export and for biogenesis of the outer membrane. Transmembrane domains (TMD) form a pore in the inner membrane and the ATP-binding domain (NBD) is responsible for energy generation. Belongs to the ABC transporter superfamily. Lipid exporter (TC 3.A.1.106) family. (582 aa)
macBMacrolide ABC transporter peremase/ATPase; Part of the tripartite efflux system MacAB-TolC. MacB is a non-canonical ABC transporter that contains transmembrane domains (TMD), which form a pore in the inner membrane, and an ATP-binding domain (NBD), which is responsible for energy generation. When overexpressed, the system confers resistance against macrolides composed of 14- and 15-membered lactones but no or weak resistance against 16-membered ones. In addition, the system could also transport R-LPS or a similar glycolipid. Belongs to the ABC transporter superfamily. Macrolide exporte [...] (648 aa)
macAMacrolide transporter membrane fusion protein (MFP) component; Part of the tripartite efflux system MacAB-TolC. MacA stimulates the ATPase activity of MacB by promoting the closed ATP- bound state of MacB, increases the capacity of MacB to bind macrolides such as erythromycin, and provides a physical link between MacB and TolC. When overexpressed, the system confers resistance against macrolides composed of 14- and 15-membered lactones but no or weak resistance against 16-membered ones. In addition, MacA binds tightly rough-core lipopolysaccharide (R-LPS), suggesting that the system co [...] (371 aa)
acrZAcrAB-TolC efflux pump accessory protein, membrane-associated; AcrA-AcrB-AcrZ-TolC is a drug efflux protein complex with a broad substrate specificity. This protein binds to AcrB and is required for efflux of some but not all substrates, suggesting it may influence the specificity of drug export. (49 aa)
acrAMultidrug efflux system; AcrA-AcrB-AcrZ-TolC is a drug efflux protein complex with broad substrate specificity that uses the proton motive force to export substrates. This subunit may act as an adapter protein that links AcrB and TolC stably together. It is elongated in shape, being long enough to span the periplasm. (397 aa)
araCAra regulon transcriptional activator; Transcription factor that regulates the expression of several genes involved in the transport and metabolism of L-arabinose. Functions both as a positive and a negative regulator. In the presence of arabinose, activates the expression of the araBAD, araE, araFGH and araJ promoters. In the absence of arabinose, negatively regulates the araBAD operon. Represses its own transcription. Acts by binding directly to DNA. (292 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)
dinFOxidative stress resistance protein; DNA-damage-inducible protein F; Protein involved in DNA repair, response to radiation and SOS response; Belongs to the multi antimicrobial extrusion (MATE) (TC 2.A.66.1) family. (459 aa)
mdtFAnaerobic multidrug efflux transporter, ArcA-regulated; Part of the tripartite efflux system MdtEF-TolC, which confers resistance to compounds such as rhodamine 6G, erythromycin, doxorubicin, ethidium bromide, TPP, SDS, deoxycholate, crystal violet and benzalkonium; Belongs to the resistance-nodulation-cell division (RND) (TC 2.A.6) family. (1037 aa)
acrFMultidrug efflux system protein; Part of the tripartite efflux system AcrEF-TolC. Involved in the efflux of indole and organic solvents. Belongs to the resistance-nodulation-cell division (RND) (TC 2.A.6) family. (1034 aa)
tolCTransport channel; Outer membrane channel, which is required for the function of several efflux systems such as AcrAB-TolC, AcrEF-TolC, EmrAB-TolC and MacAB-TolC. These systems are involved in export of antibiotics and other toxic compounds from the cell. TolC is also involved in import of colicin E1 into the cells. (493 aa)
emrBMultidrug efflux system protein; Part of the tripartite efflux system EmrAB-TolC, which confers resistance to antibiotics such as CCCP, FCCP, 2,4-dinitrophenol and nalidixic acid. (512 aa)
emrAMultidrug efflux system; Part of the tripartite efflux system EmrAB-TolC, which confers resistance to antibiotics such as CCCP, FCCP, 2,4-dinitrophenol and nalidixic acid. EmrA is a drug-binding protein that provides a physical link between EmrB and TolC; Belongs to the membrane fusion protein (MFP) (TC 8.A.1) family. (390 aa)
acrDAminoglycoside/multidrug efflux system; Participates in the efflux of aminoglycosides. Confers resistance to a variety of these substances. Belongs to the resistance-nodulation-cell division (RND) (TC 2.A.6) family. (1037 aa)
mepAMurein DD-endopeptidase; Murein endopeptidase that cleaves the D-alanyl-meso-2,6- diamino-pimelyl amide bond that connects peptidoglycan strands. Likely plays a role in the removal of murein from the sacculus and could also play a role in the integration of nascent murein strands into the sacculus. (274 aa)
gyrADNA gyrase (type II topoisomerase), subunit A; A type II topoisomerase that negatively supercoils closed circular double-stranded (ds) DNA in an ATP-dependent manner to maintain chromosomes in an underwound state. This makes better substrates for topoisomerase IV (ParC and ParE) which is the main enzyme that unlinks newly replicated chromosomes in E.coli. Gyrase catalyzes the interconversion of other topological isomers of dsDNA rings, including catenanes. Relaxes negatively supercoiled DNA in an ATP-independent manner. E.coli gyrase has higher supercoiling activity than many other bac [...] (875 aa)
sdiAQuorum-sensing transcriptional activator; Activates cell division by specifically increasing transcription from one of the two promoters that lie immediately upstream of the ftsQAZ gene cluster. Activates ydiV expression in response to extracellular autoinducer AI-1 (Vibrio fischeri autoinducer oxoC6). (240 aa)
mdtKMultidrug efflux system transporter; Multidrug efflux pump that probably functions as a Na(+)/drug antiporter. Confers resistance to many drugs such as fluoroquinolones (norfloxacin, ciprofloxacin, enoxacin) and tetraphenylphosphonium ion (TPP). Also to deoxycholate, doxorubicin, trimethoprim, chloramphenicol, fosfomycin, ethidium bromide and benzalkonium. Also able to export peptides; when overexpressed, allows cells deleted for multiple peptidases (pepA, pepB, pepD and pepN) to grow in the presence of dipeptides Ala-Gln or Gly-Tyr which otherwise inhibit growth. Cells overexpressing [...] (457 aa)
marAMultiple antibiotic resistance transcriptional regulator; 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. (127 aa)
