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

sdhBSuccinate dehydrogenase, iron-sulfur subunit; Belongs to the succinate dehydrogenase/fumarate reductase iron-sulfur protein family. (259 aa)    
Predicted Functional Partners:
sdhC
Succinate dehydrogenase, cytochrome b556 subunit.
 
 0.999
sdhD
Succinate dehydrogenase, hydrophobic membrane anchor protein.
  
 0.999
sdhA
Succinate dehydrogenase, flavoprotein subunit; Belongs to the FAD-dependent oxidoreductase 2 family. FRD/SDH subfamily.
 
 0.999
sucD
succinyl-CoA synthetase (ADP-forming), alpha subunit; 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.
 
 0.995
sucC
succinyl-CoA synthetase (ADP-forming), beta subunit; 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.
 
 0.993
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.
  
 0.979
petA
Ubiquinol--cytochrome-c reductase, iron-sulfur subunit; Component of the ubiquinol-cytochrome c reductase complex (complex III or cytochrome b-c1 complex), which is a respiratory chain that generates an electrochemical potential coupled to ATP synthesis. Belongs to the Rieske iron-sulfur protein family.
 
 
 0.973
nuoI
NADH-quinone oxidoreductase, I 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.
  
 
 0.945
sucA
Oxoglutarate dehydrogenase (succinyl-transferring), E1 component.
 
 
 0.939
petC
Ubiquinol--cytochrome-c reductase, cytochrome c1 subunit; Component of the ubiquinol-cytochrome c reductase complex (complex III or cytochrome b-c1 complex), which is a respiratory chain that generates an electrochemical potential coupled to ATP synthesis. c1 functions as an electron donor to cytochrome c.
