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

tfrAThiol:fumarate reductase, subunit A; Catalyzes the reduction of fumarate with reduced coenzyme M (CoM-S-H) and coenzyme B (CoB-S-H). In vitro, is able to reduces fumarate with reduced benzyl viologen, oxidize CoM-S-H and CoB-S-H to CoM-S-S-CoB with methylene blue, and reduce CoM-S-S-CoB with reduced benzyl viologen. The enzyme has specificity for the two thiol compounds as the CoB--CoM heterodisulfide reductase. The enzyme is very sensitive to oxygen; Belongs to the FAD-dependent oxidoreductase 2 family. (547 aa)    
Predicted Functional Partners:

ADL57744.1
Predicted NADH dehydrogenase.
  
 
 0.994
sucD
succinyl-CoA synthase, 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.
 
 0.993
sucC
succinyl-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.
