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

CCQ72646.1
Cytochrome b; Component of the ubiquinol-cytochrome c reductase complex (complex III or cytochrome b-c1 complex), which is a respiratory chain that generates an electrochemical potential coupled to ATP synthesis.
 
 
 0.991
ctaB

nuoM
NADH-quinone oxidoreductase chain M (NADH dehydrogenase I, chain M) (NDH-1, chain M); Function of homologous gene experimentally demonstrated in an other organism; enzyme.
  
 
 0.967
fixP
Cytochrome-c oxidase fixP chain; C-type cytochrome. Part of the cbb3-type cytochrome c oxidase complex.
  
 0.966
CCQ74688.1
Putative cytochrome c oxidase, subunit I; Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative enzyme.
 
  
  0.964
nuoH
NADH-quinone oxidoreductase chain H (NADH dehydrogenase I, chain H) (NDH-1, chain H); 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. This subunit may bind ubiquinone.
