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 aa3-600 quinol oxidase (subunit I); Catalyzes quinol oxidation with the concomitant reduction of oxygen to water. Major component for energy conversion during vegetative growth (By similarity). (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
ctaE
Cytochrome caa3 oxidase (subunit III); Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme; Belongs to the cytochrome c oxidase subunit 3 family.
 0.999
qoxD
Cytochrome aa3-600 quinol oxidase (subunit IV); Catalyzes quinol oxidation with the concomitant reduction of oxygen to water. Major component for energy conversion during vegetative growth (By similarity).
 
 0.999
qoxC
Cytochrome aa3-600 quinol oxidase (subunit III); Catalyzes quinol oxidation with the concomitant reduction of oxygen to water. Major component for energy conversion during vegetative growth (By similarity).
 0.999
qoxA
Cytochrome aa3-600 quinol oxidase (subunit II); Catalyzes quinol oxidation with the concomitant reduction of oxygen to water. Major component for energy conversion during vegetative growth. Subunit II transfers the electrons from a quinol to the binuclear center of the catalytic subunit I (By similarity).
 
 0.999
ctaB
Protoheme IX farnesyltransferase 2; 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.
 0.998
ctaO
Minor protoheme IX farnesyltransferase 1 (heme O synthase); 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.
 
 0.993
ctaF
Cytochrome caa3 oxidase (subunit IV); Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme; Belongs to the cytochrome c oxidase bacterial subunit 4 family.
  
 0.988
qcrB
Menaquinol:cytochrome c oxidoreductase (cytochrome b subunit); Component of the menaquinol-cytochrome c reductase complex.
 
 
 0.944
qcrC
Menaquinol:cytochrome c oxidoreductase (cytochrome cc subunit); Component of the menaquinol-cytochrome c reductase complex.
