STRINGSTRING
STRING protein interaction network
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

frdB_2Fumarate reductase; Derived by automated computational analysis using gene prediction method: Protein Homology. (243 aa)    
Predicted Functional Partners:
frdA_1
Part of four member fumarate reductase enzyme complex FrdABCD which catalyzes the reduction of fumarate to succinate during anaerobic respiration; FrdAB are the catalytic subcomplex consisting of a flavoprotein subunit and an iron-sulfur subunit, respectively; FrdCD are the membrane components which interact with quinone and are involved in electron transfer; the catalytic subunits are similar to succinate dehydrogenase SdhAB; Derived by automated computational analysis using gene prediction method: Protein Homology.

frdC
Fumarate reductase; Derived by automated computational analysis using gene prediction method: Protein Homology.
 
 0.999
frdD
Fumarate reductase; Seems to be involved in the anchoring of the catalytic components of the fumarate reductase complex to the cytoplasmic membrane.
 
 0.998
sucD_1
succinyl-CoA synthetase subunit alpha; Catalyzes the only substrate-level phosphorylation in the TCA cycle; Derived by automated computational analysis using gene prediction method: Protein Homology.
 
 0.992
sucC
succinyl-CoA synthetase subunit beta; Catalyzes the interconversion of succinyl-CoA and succinate; Derived by automated computational analysis using gene prediction method: Protein Homology.
 
 0.988
fumC
Fumarate hydratase; Involved in the TCA cycle. Catalyzes the stereospecific interconversion of fumarate to L-malate; Belongs to the class-II fumarase/aspartase family. Fumarase subfamily.
  
 0.957
gabD
Succinate-semialdehyde dehydrogenase; Catalyzes the formation of succinate from succinate semialdehyde; NADP dependent; Derived by automated computational analysis using gene prediction method: Protein Homology.
   
 
 0.910
nfuA
Amino acid ABC transporter substrate-binding protein; Involved in iron-sulfur cluster biogenesis. Binds a 4Fe-4S cluster, can transfer this cluster to apoproteins, and thereby intervenes in the maturation of Fe/S proteins. Could also act as a scaffold/chaperone for damaged Fe/S proteins.
  
 
 0.898
gltA
Type II enzyme; in Escherichia coli this enzyme forms a trimer of dimers which is allosterically inhibited by NADH and competitively inhibited by alpha-ketoglutarate; allosteric inhibition is lost when Cys206 is chemically modified which also affects hexamer formation; forms oxaloacetate and acetyl-CoA and water from citrate and coenzyme A; functions in TCA cycle, glyoxylate cycle and respiration; enzyme from Helicobacter pylori is not inhibited by NADH; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the citrate synthase family.
 
 
 0.871
sucA_2
2-oxoglutarate dehydrogenase; Derived by automated computational analysis using gene prediction method: Protein Homology.
  
 
 0.854
