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

sdhASuccinate dehydrogenase/fumarate reductase, flavoprotein subunit. (648 aa)    
Predicted Functional Partners:
sdhB
Succinate dehydrogenase/fumarate reductase, Fe-S protein subunit.
 
 0.999
sdhC
Succinate dehydrogenase cytochrome b-556 subunit.
 
 
 0.999
sdhb
Succinate dehydrogenase/fumarate reductase, Fe-S protein subunit.
  
 0.997
fumB
Fumarate hydratase, class I; Catalyzes the reversible hydration of fumarate to (S)-malate. Belongs to the class-I fumarase family.
  
 
 0.992
sucC
succinyl-CoA synthetase subunit beta; 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.
 
 0.984
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.
  
 0.980
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.
 
 0.973
sucA
2-oxoglutarate dehydrogenase complex, dehydrogenase (E1) component, and related enzymes.
 
 
 0.969
gabD
Succinate-semialdehyde dehydrogenase (NADP+); NAD-dependent aldehyde dehydrogenases; Belongs to the aldehyde dehydrogenase family.
   
 0.926
ACPL_4079
Succinate-semialdehyde dehydrogenase (NADP+); NAD-dependent aldehyde dehydrogenases; Belongs to the aldehyde dehydrogenase family.
   
 0.926
