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

sdhAThis HMM represents the succinate dehydrogenase flavoprotein subunit as found in the low-GC Gram-positive bacteria and a few other lineages. This enzyme may act in a complete or partial TCA cycle, or act in the opposite direction as fumarate reductase. (583 aa)    
Predicted Functional Partners:
sdhC
Succinate dehydrogenase (cytochrome b558 subunit).
 
 0.999
sdhB
Succinate dehydrogenase/fumarate reductase iron-sulfur protein.
 
 0.999
sucD
Succinyl-coa synthetase alpha chain 2; 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.
 0.996
sucC
Succinyl-coa synthase, 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.
 0.995
nuoF
Proton-translocating NADH-ubiquinone oxidoreductase, chain f.
  
 
 0.987
HM1_1028
NADH dehydrogenase conserved domain protein, nuoe and nuof.
  
 
 0.981
HM1_2651
Uncharacterized protein ygfk; May contain a pyridine nucleotide-disulfide oxidoreductase domain and a 4Fe-4S binding domain.
  
 
 0.968
ttdA
Tartrate dehydratase alpha subunit/fumarate hydratase.
  
 
 0.967
fumB
Fumarate hydratase, beta subunit.
  
 
 0.967
HM1_0345
acetyl-CoA hydrolase, putative.
   
 
 0.911
