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

sdhCSuccinate dehydrogenase cytochrome b-556 subunit. (83 aa)    
Predicted Functional Partners:
sdhD
Succinate dehydrogenase hydrophobic membrane anchor subunit; Membrane-anchoring subunit of succinate dehydrogenase (SDH).
 
 0.999
sdhB
Succinate dehydrogenase iron sulfur protein; Belongs to the succinate dehydrogenase/fumarate reductase iron-sulfur protein family.
 
 0.999
sdhA
Succinate dehydrogenase flavoprotein subunit; Belongs to the FAD-dependent oxidoreductase 2 family. FRD/SDH subfamily.
 
 0.998
frdA
Fumarate reductase flavoprotein subunit.
  
 0.996
frdB
Fumarate reductase iron-sulfur protein; Belongs to the succinate dehydrogenase/fumarate reductase iron-sulfur protein family.
  
 0.996
sucC
succinyl-CoA synthetase beta chain; 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 beta subunit provides nucleotide specificity of the enzyme and binds the substrate succinate, while the binding sites for coenzyme A and phosphate are found in the alpha subunit.
  
 
 0.990
nuoC
NADH dehydrogenase I chain C/D (NADH-ubiquinone oxidoreductase chain 3/4) (NUO3/NUO4); 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; In the N-terminal section; belongs to the complex I 30 kDa subunit family.
  
 
 0.981
sucD
succinyl-CoA synthetase alpha chain; 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.
  
 
 0.977
fumC
Fumarate hydratase class II (fumarase); Involved in the TCA cycle. Catalyzes the stereospecific interconversion of fumarate to L-malate; Belongs to the class-II fumarase/aspartase family. Fumarase subfamily.
   
 
 0.958
frdD
Fumarate reductase 13 kDa hydrophobic protein; Seems to be involved in the anchoring of the catalytic components of the fumarate reductase complex to the cytoplasmic membrane.
     
 0.916
