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

frdDFumarate reductase (anaerobic), membrane anchor subunit; Seems to be involved in the anchoring of the catalytic components of the fumarate reductase complex to the cytoplasmic membrane; Belongs to the FrdD family. (119 aa)    
Predicted Functional Partners:
frdC
Fumarate reductase (anaerobic), membrane anchor subunit; Seems to be involved in the anchoring of the catalytic components of the fumarate reductase complex to the cytoplasmic membrane.
 
 0.999
frdB
Fumarate reductase (anaerobic), Fe-S subunit; Two distinct, membrane-bound, FAD-containing enzymes are responsible for the catalysis of fumarate and succinate interconversion; the fumarate reductase is used in anaerobic growth, and the succinate dehydrogenase is used in aerobic growth.
 
 0.999
frdA
Anaerobic fumarate reductase catalytic and NAD/flavoprotein subunit; Two distinct, membrane-bound, FAD-containing enzymes are responsible for the catalysis of fumarate and succinate interconversion; the fumarate reductase is used in anaerobic growth, and the succinate dehydrogenase is used in aerobic growth. Belongs to the FAD-dependent oxidoreductase 2 family. FRD/SDH subfamily.

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. Can use either ATP or GTP, but prefers ATP. It can also function in the other direction for anabolic purposes, and this may be particularly impor [...]

sucD
succinyl-CoA synthetase, NAD(P)-binding, alpha 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 alpha subunit of the enzyme binds the substrates coenzyme A and phosphate, while succinate binding and nucleotide specificity is provided by the beta subunit. Can use either ATP or GTP, but prefers ATP. It can also function in the other direction for anabolic purposes, and this may be particularly importan [...]

gabD
Succinate-semialdehyde dehydrogenase I, NADP-dependent; Catalyzes the NADP(+)-dependent oxidation of succinate semialdehyde to succinate. Thereby functions in a GABA degradation pathway that allows some E.coli strains to utilize GABA as a nitrogen source for growth. Also catalyzes the conversion of glutarate semialdehyde to glutarate, as part of a L- lysine degradation pathway that proceeds via cadaverine, glutarate and L-2-hydroxyglutarate.
