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

frdBPart of three member fumarate reductase enzyme complex FrdABC which catalyzes the reduction of fumarate to succinate during anaerobic respiration; FrdAB are the catalytic subcomplex consisting of a flavoprotein subunit and an iron-sulfur subunit, respectively; FrdC is the cytochrome b-556 subunit; the catalytic subunits are similar to succinate dehydrogenase SdhAB; Derived by automated computational analysis using gene prediction method: Protein Homology. (255 aa)

sdhA
Part of four member succinate dehydrogenase enzyme complex that forms a trimeric complex (trimer of tetramers); SdhA/B are the catalytic subcomplex and can exhibit succinate dehydrogenase activity in the absence of SdhC/D which are the membrane components and form cytochrome b556; SdhC binds ubiquinone; oxidizes succinate to fumarate while reducing ubiquinone to ubiquinol; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the FAD-dependent oxidoreductase 2 family. FRD/SDH subfamily.

sucD
succinyl-CoA synthetase subunit 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.
 
 0.990
sucC
malate--CoA ligase 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.

Adenylylsulfate reductase subunit alpha; Catalyzes the reduction of adenosine 5'-phosphosulfate to AMP and sulfite; Derived by automated computational analysis using gene prediction method: Protein Homology.
 
 0.973
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.
