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 b558 subunit); Di-heme cytochrome of the succinate dehydrogenase complex. (202 aa)    
Predicted Functional Partners:
ctaC
Cytochrome caa3 oxidase (subunit II); Subunits I and II form the functional core of the enzyme complex. Electrons originating in cytochrome c are transferred via heme a and Cu(A) to the binuclear center formed by heme a3 and Cu(B).
   
 
 0.999
sucC
succinyl-CoA synthetase (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.
 
 
 0.999
sdhB
Succinate dehydrogenase (iron-sulfur protein); Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme; Belongs to the succinate dehydrogenase/fumarate reductase iron-sulfur protein family.
 
 0.999
sdhA
Succinate dehydrogenase (flavoprotein subunit); Evidence 2a: Function of homologous gene experimentally demonstrated in an other organism; enzyme.
 
 0.999
sucD
succinyl-CoA synthetase (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.
 
 
 0.997
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.
   
 
 0.986
odhA
2-oxoglutarate dehydrogenase (E1 subunit); E1 component of the 2-oxoglutarate dehydrogenase (OGDH) complex which catalyzes the decarboxylation of 2-oxoglutarate, the first step in the conversion of 2-oxoglutarate to succinyl-CoA and CO(2).
  
  
 0.980
qcrA
Menaquinol:cytochrome c oxidoreductase (iron-sulfur subunit); Component of the menaquinol-cytochrome c reductase complex. The Rieske protein is a high potential 2Fe-2S protein.
 
  
 0.930
gabD
Succinate-semialdehyde dehydrogenase; Catalyzes the NADP(+) dependent oxidation of succinate semialdehyde to succinate.
   
 
  0.905
yhfW
Putative Rieske [2Fe-2S] oxygenase; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pe: putative enzyme.
  
  
 0.897
