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:
nfoEndonuclease IV with intrinsic 3'-5' exonuclease activity; Endonuclease IV plays a role in DNA repair. It cleaves phosphodiester bonds at apurinic or apyrimidinic (AP) sites, generating a 3'-hydroxyl group and a 5'-terminal sugar phosphate. It preferentially attacks modified AP sites created by bleomycin and neocarzinostatin. (285 aa)
ybjCDUF1418 family protein. (95 aa)
nfsBDihydropteridine reductase, NAD(P)H-dependent, oxygen-insensitive; Reduction of a variety of nitroaromatic compounds using NADH (and to lesser extent NADPH) as source of reducing equivalents; two electrons are transferred. Capable of reducing nitrofurazone, quinones and the anti-tumor agent CB1954 (5-(aziridin-1-yl)-2,4- dinitrobenzamide). The reduction of CB1954 results in the generation of cytotoxic species; Belongs to the nitroreductase family. (217 aa)
gyrBDNA gyrase, subunit B; DNA gyrase negatively supercoils closed circular double- stranded DNA in an ATP-dependent manner to maintain chromosomes in an underwound state. This makes better substrates for topoisomerase 4 (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 double-stranded DNA rings, including catenanes. Relaxes negatively supercoiled DNA in an ATP-independent manner. E.coli gyrase has higher supercoiling activity than other characterized bacterial gyrases; at compa [...] (804 aa)
ybjNNegative regulator of motility; Putative sensory transduction regulator. (158 aa)
marBPeriplasmic mar operon regulator; Multiple antibiotic resistance protein; Protein involved in response to drug and xenobiotic metabolic process. (72 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)
acrBMultidrug efflux system protein; AcrA-AcrB-AcrZ-TolC is a drug efflux protein complex with broad substrate specificity that uses the proton motive force to export substrates. (1049 aa)
mltFMembrane-bound lytic transglycosylase F, murein hydrolase; Murein-degrading enzyme that degrades murein glycan strands and insoluble, high-molecular weight murein sacculi, with the concomitant formation of a 1,6-anhydromuramoyl product. Lytic transglycosylases (LTs) play an integral role in the metabolism of the peptidoglycan (PG) sacculus. Their lytic action creates space within the PG sacculus to allow for its expansion as well as for the insertion of various structures such as secretion systems and flagella. (518 aa)
inaAAcid-inducible Kdo/WaaP family putative kinase; May be an environmental sensor responsive to several stimuli, including internal pH, proton motive force, temperature, and possibly other unknown factors; Belongs to the protein kinase superfamily. KdkA/RfaP family. (216 aa)
ygiBDUF1190 family protein; Belongs to the UPF0441 family. (223 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)
rimKRibosomal protein S6 modification protein; Is an L-glutamate ligase that catalyzes the ATP-dependent post-translational addition of glutamate residues to the C-terminus of ribosomal protein S6 (RpsF). Is also able to catalyze the synthesis of poly-alpha-glutamate in vitro, via ATP hydrolysis from unprotected glutamate as substrate. The number of glutamate residues added to either RpsF or to poly-alpha-glutamate changes with pH. Belongs to the RimK family. (300 aa)
nfsANitroreductase A, NADPH-dependent, FMN-dependent; Catalyzes the reduction of nitroaromatic compounds using NADPH. Has a broad electron acceptor specificity. Reduces nitrofurazone by a ping-pong bi-bi mechanism possibly to generate a two-electron transfer product. Major oxygen-insensitive nitroreductase in E.coli. (240 aa)
robRight oriC-binding transcriptional activator, AraC family; Binds to the right arm of the replication origin oriC of the chromosome. Rob binding may influence the formation of the nucleoprotein structure, required for oriC function in the initiation of replication. (289 aa)
ygiCATP-Grasp family ATPase; May be a ligase forming an amide bond. Shows ATPase activity. Despite its similarity to the C-terminal synthetase domain of Gss, is not a glutathionylspermidine (Gsp) synthetase. Cannot synthesize Gsp, glutathione (GSH), or GSH intermediates, from GSH and spermidine, cysteine and glutamate, gamma-glutamylcysteine and spermidine, and gamma-glutamylcysteine and glycine. Does not bind to Gsp. Belongs to the glutathionylspermidine synthase preATP-grasp family. (386 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)
marRTranscriptional repressor of multiple antibiotic resistance; 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)
zwfGlucose-6-phosphate 1-dehydrogenase; Catalyzes the oxidation of glucose 6-phosphate to 6- phosphogluconolactone; Belongs to the glucose-6-phosphate dehydrogenase family. (491 aa)
