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

sucCsuccinyl-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. (385 aa)    
Predicted Functional Partners:
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.

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).
 0.999
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.

sdhA
Succinate dehydrogenase (flavoprotein subunit); Evidence 2a: Function of homologous gene experimentally demonstrated in an other organism; enzyme.
 0.999
sdhC
Succinate dehydrogenase (cytochrome b558 subunit); Di-heme cytochrome of the succinate dehydrogenase complex.
 
 
 0.999
odhB
2-oxoglutarate dehydrogenase complex (dihydrolipoamide transsuccinylase, E2 subunit); E2 component of the 2-oxoglutarate dehydrogenase (OGDH) complex which catalyzes the second step in the conversion of 2- oxoglutarate to succinyl-CoA and CO(2).
 0.997
icd
Isocitrate dehydrogenase; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme.
 
  
 0.982
citZ
Citrate synthase II; Might regulate the synthesis and function of enzymes involved in later enzymatic steps of Krebs cycle. Loss in activity results in sporulation defect; Belongs to the citrate synthase family.
  
 
 0.965
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.
  
 0.964
pdhC
Pyruvate dehydrogenase (dihydrolipoamide acetyltransferase E2 subunit); The pyruvate dehydrogenase complex catalyzes the overall conversion of pyruvate to acetyl-CoA and CO(2). It contains multiple copies of three enzymatic components: pyruvate dehydrogenase (E1), dihydrolipoamide acetyltransferase (E2) and lipoamide dehydrogenase (E3).
