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

frdBQuinol:fumarate reductase FeS subunit FrdB. (243 aa)    
Predicted Functional Partners:
frdC
Quinol:fumarate reductase menaquinol-oxidizing subunit FrdC.
 
 0.999
frdC-2
Quinol:fumarate reductase menaquinol-oxidizing subunit FrdC.
 
 0.999
frdA
Quinol:fumarate reductase FAD-binding subunit FrdA.
 0.999
sdhA
Succinate dehydrogenase flavoprotein subunit SdhA; Belongs to the FAD-dependent oxidoreductase 2 family. FRD/SDH subfamily.
 0.998
sdhD
Succinate dehydrogenase membrane anchor subunit SdhD; Membrane-anchoring subunit of succinate dehydrogenase (SDH).
  
 0.997
sdhC
Succinate dehydrogenase cytochrome b556 subunit SdhC.
  
 0.993
fccA
Periplasmic fumarate reductase FccA; Catalyzes fumarate reduction using artificial electron donors such as methyl viologen. The physiological reductant is unknown, but evidence indicates that flavocytochrome c participates in electron transfer from formate to fumarate and possibly also to trimethylamine oxide (TMAO). This enzyme is essentially unidirectional (By similarity); In the C-terminal section; belongs to the FAD-dependent oxidoreductase 2 family. FRD/SDH subfamily.
 
 0.990
ifcA
Periplasmic tetraheme flavocytochrome IfcA; Belongs to the FAD-dependent oxidoreductase 2 family. FRD/SDH subfamily.
 
 0.987
fumB
Anaerobic fumarate hydratase FumB; Catalyzes the reversible hydration of fumarate to (S)-malate. Belongs to the class-I fumarase family.
  
 
 0.987
nuoCD
NADH-ubiquinone oxidoreductase subunit CD NuoCD; NDH-1 shuttles electrons from NADH, via FMN and iron-sulfur (Fe-S) centers, to quinones in the respiratory chain. The immediate electron acceptor for the enzyme in this species is believed to be ubiquinone. Couples the redox reaction to proton translocation (for every two electrons transferred, four hydrogen ions are translocated across the cytoplasmic membrane), and thus conserves the redox energy in a proton gradient; In the N-terminal section; belongs to the complex I 30 kDa subunit family.
