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

frdAFumarate reductase/succinate dehydrogenase, flavoprotein subunit. (539 aa)    
Predicted Functional Partners:
MMP1067
Uncharacterized iron-sulfur protein MMP1067; Succinate dehydrogenase/fumarate reductase iron-sulfur subunit // Methanosarcina type heterodisulfide reductase subunit D; Belongs to the succinate dehydrogenase/fumarate reductase iron-sulfur protein family.
 
 0.998
sucD
succinate--CoA ligase (ADP-forming); Succinyl-CoA synthetase functions in the citric acid cycle (TCA), coupling the hydrolysis of succinyl-CoA to the synthesis of either ATP or GTP and thus represents the only step of substrate-level phosphorylation in the TCA. The alpha subunit of the enzyme binds the substrates coenzyme A and phosphate, while succinate binding and nucleotide specificity is provided by the beta subunit.
 0.997
sucC
succinate-CoA ligase (ADP-forming), beta chain.
 0.996
fumA
Fumarate hydratase.
  
 
 0.986
MMP1548
Fe-S type hydro-lyases tartrate/fumarate beta region.
  
 
 0.986
ehbL
Ferredoxin; Citation: Tersteegen, A. and R. Hedderich. 1999. Eur. J. Biochem. 264:930-43.
  
 
 0.972
nadC
Quinolinate phosphoribosyl transferase:Nicotinate-nucleotide pyrophosphorylase; Involved in the catabolism of quinolinic acid (QA). Belongs to the NadC/ModD family.
   
 0.942
mdh
Malate dehydrogenase, MDHII (NADP+-dependent); Catalyzes the reversible oxidation of malate to oxaloacetate.
 
 
 0.920
iorA2
Indolepyruvate oxidoreductase subunit alpha 2; Catalyzes the ferredoxin-dependent oxidative decarboxylation of arylpyruvates.
  
 
 0.914
fdxA
Ferredoxin.
  
 
 0.913
