STRING protein interaction network
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:
some 3D structure is known or predicted
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
protein homology
Your Input:
Gene Fusion
aegAPutative oxidoreductase, fes binding subunit/nad/fad-binding subunit; Protein AegA; Putative enzyme; Not classified (659 aa)    
Predicted Functional Partners:
Glutamate synthase (nadph) large chain; Catalyzes the conversion of L-glutamine and 2-oxoglutarate into two molecules of L-glutamate
Gdp-mannose pyrophosphatase nudk; Nucleoside diphosphate sugar hydrolase that hydrolyzes GDP- mannose as its preferred substrate, yielding GMP and mannose-1- phosphate. Can also hydrolyze the pyrophosphate bond of other sugar nucleotides such as IDP-ribose, GDP-glucose, and to a lesser extent, ADP-ribose, ADP-glucose and UDP-glucose. Shows no activity toward Nudix substrates FAD, CDP-ethanolamine, CDP-choline, NAD(+), diadenosine pentaphosphate, GTP, UTP, ATP, or CTP
Pyruvate-ferredoxin/flavodoxin oxidoreductase; Oxidoreductase required for the transfer of electrons from pyruvate to flavodoxin
Dihydropyrimidine dehydrogenase, nadh-dependent, subunit c; Involved in pyrimidine base degradation. Catalyzes physiologically the reduction of uracil to 5,6-dihydrouracil (DHU) by using NADH as a specific cosubstrate. It also catalyzes the reverse reaction and the reduction of thymine to 5,6-dihydrothymine (DHT)
Nadh:ubiquinone oxidoreductase, fused cd subunit; NDH-1 shuttles electrons from NADH, via FMN and iron-sulfur (Fe-S) centers, to quinones in the respiratory chain. The immediate electron acceptor for the enzyme in this species is believed to be ubiquinone. Couples the redox reaction to proton translocation (for every two electrons transferred, four hydrogen ions are translocated across the cytoplasmic membrane), and thus conserves the redox energy in a proton gradient
Two-component system, narl family, nitrate/nitrite sensor histidine kinase narq; Acts as a sensor for nitrate/nitrite and transduces signal of nitrate/nitrite availability to the NarL/NarP proteins. NarQ probably activates NarL and NarP by phosphorylation. NarQ probably negatively regulates the NarL protein by dephosphorylation
Ferredoxin-type protein, role in electron transfer to periplasmic nitrate reductase napa; Could be involved in the maturation of NapA, the catalytic subunit of the periplasmic nitrate reductase, before its export into the periplasm . Is not involved in the electron transfer from menaquinol or ubiquinol to the periplasmic nitrate reductase
Hu, dna-binding transcriptional regulator, alpha subunit; Histone-like DNA-binding protein which is capable of wrapping DNA to stabilize it, and thus to prevent its denaturation under extreme environmental conditions
[2Fe-2S] ferredoxin; Ferredoxin are iron-sulfur proteins that transfer electrons in a wide variety of metabolic reactions. Although the function of this ferredoxin is unknown it is probable that it has a role as a cellular electron transfer protein. Involved in the in vivo assembly of the Fe-S clusters in a wide variety of iron-sulfur proteins
Sugar phosphate phosphatase; Catalyzes the dephosphorylation of different sugar phosphates including erythrose-4-phosphate (Ery4P), ribose-5-phosphate (Ribu5P), fructose-1-phosphate (Fru1P), fructose-6-phosphate (Fru6P), glucose-6-P (Glu6P), and also imidodiphosphate (Imido-di-P) and acetyl phosphate (Acetyl-P). Selectively hydrolyzes alpha-D-glucose-1-phosphate (Glu1P) and has no activity with the beta form
