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. (364 aa)    
Predicted Functional Partners:
sucD
succinyl-CoA synthetase, alpha subunit (sucD); 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.

MJ_0211
UDP-glucose 4-epimerase (galE); Involved in the metabolism of galactose. Catalyzes the conversion of UDP-galactose (UDP-Gal) to UDP-glucose (UDP-Glc) through a mechanism involving the transient reduction of NAD (By similarity). Belongs to the NAD(P)-dependent epimerase/dehydratase family.

mdh
L-lactate dehydrogenase EGAD|7256|705; Catalyzes the reversible oxidation of (S)-malate and (S)- sulfolactate to oxaloacetate and sulfopyruvate, respectively. Can use both NADH and NADPH, although activity is higher with NADPH. Oxidation of (S)-sulfolactate is observed only in the presence of NADP(+). Can also oxidize tartrate. Cannot reduce pyruvate, nor alpha-ketoglutarate. Belongs to the LDH/MDH superfamily.
