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 QoxB; Belongs to the heme-copper respiratory oxidase family. (647 aa)    
Predicted Functional Partners:
qoxC
Cytochrome aa3 quinol oxidase subunit III QoxC.
 
 0.999
qoxA
Cytochrome aa3 quinol oxidase subunit II QoxA; 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.
 
 0.999
ctaC
Cytochrome caa3 oxidase subunit II CoxB; 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
qoxD
Cytochrome aa3 quinol oxidase subunit IV QoxD.
 
 0.998
ctaE
Cytochrome caa3 oxidase subunit III CoxC.
 0.998
ctaB
Cytochrome oxidase 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.
 
 0.995
ctaF
Cytochrome caa3 oxidase subunit IV CoxD.
  
 0.989
qcrB
Menaquinol-cytochrome c reductase cytochrome b subunit.
 
 
 0.916
ctaD
Cytochrome caa3 oxidase subunit I CoxA; Cytochrome c oxidase is the component of the respiratory chain that catalyzes the reduction of oxygen to water. Subunits 1-3 form the functional core of the enzyme complex. CO I is the catalytic subunit of the enzyme. Electrons originating in cytochrome c are transferred via the copper A center of subunit 2 and heme A of subunit 1 to the bimetallic center formed by heme A3 and copper B.
  
  
 
0.904
qcrC
Menaquinol-cytochrome c reductase cytochrome b/c subunit; Component of the menaquinol-cytochrome c reductase complex.
  
 
 0.900
