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

qoxBCytochrome aa3 quinol oxidase (subunit I); Belongs to the heme-copper respiratory oxidase family. (649 aa)    
Predicted Functional Partners:
ctaC
Cytochrome caa3 oxidase (subunit II); Subunits I and II form the functional core of the enzyme complex. Electrons originating in cytochrome c are transferred via heme a and Cu(A) to the binuclear center formed by heme a3 and Cu(B).
 
 0.999
qoxA
Cytochrome aa3 quinol oxidase (subunit II); Catalyzes quinol oxidation with the concomitant reduction of oxygen to water. Subunit II transfers the electrons from a quinol to the binuclear center of the catalytic subunit I.
 
 0.998
qoxC
Cytochrome aa3 quinol oxidase (subunit III).
 0.998
qoxD
Cytochrome aa3 quinol oxidase (subunit IV).
 
 0.996
ctaE
Cytochrome caa3 oxidase (subunit III).
 
 0.993
ctaB
Cytochrome caa3 oxydase assembly factor; Converts heme B (protoheme IX) to heme O by substitution of the vinyl group on carbon 2 of heme B porphyrin ring with a hydroxyethyl farnesyl side group; Belongs to the UbiA prenyltransferase family. Protoheme IX farnesyltransferase subfamily.
 
 0.980
ctaF
Cytochrome caa3 oxidase (subunit IV).
  
 0.969
qcrB
Menaquinol:cytochrome c oxidoreductase (cytochrome b subunit).
 
 0.942
BL03212
Conservd hypothetical protein.
  
 0.930
qcrC
Menaquinol:cytochrome c oxidoreductase (cytochrome b/c subunit); Component of the menaquinol-cytochrome c reductase complex.
  
 0.930
