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

sucCProbable succinyl-CoA synthetase (beta chain) SucC (SCS-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. (387 aa)    
Predicted Functional Partners:
sucD
Probable succinyl-CoA synthetase (alpha chain) SucD (SCS-alpha); 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.

kgd
Multifunctional alpha-ketoglutarate metabolic enzyme; Shows three enzymatic activities that share a first common step, the attack of thiamine-PP on 2-oxoglutarate (alpha-ketoglutarate, KG), leading to the formation of an enamine-thiamine-PP intermediate upon decarboxylation. Thus, displays KGD activity, catalyzing the decarboxylation from five-carbon 2-oxoglutarate to four-carbon succinate semialdehyde (SSA). Also catalyzes C-C bond formation between the activated aldehyde formed after decarboxylation of alpha- ketoglutarate and the carbonyl of glyoxylate (GLX), to yield 2-hydroxy- 3-o [...]

sdhC
Succinate dehydrogenase 2 membrane subunit SdhC; Membrane-anchoring subunit of succinate dehydrogenase 2 (Sdh2). Sdh2 may catalyze the two-electron oxidation of succinate to fumarate with a corresponding reduction of quinone to quinol under low oxygen conditions, when the primary aerobic succinate dehydrogenase (Sdh1) is inhibited. Sdh2 seems to be the generator of the proton motive force (PMF) under hypoxia.
