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

ctaFCytochrome caa3 oxidase subunit IV CoxD. (115 aa)    
Predicted Functional Partners:
ctaE
Cytochrome caa3 oxidase subunit III CoxC.
 
 0.999
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.
 
 0.997
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).
 
 0.997
qoxC
Cytochrome aa3 quinol oxidase subunit III QoxC.
  
 0.989
qoxB
Cytochrome aa3 quinol oxidase subunit I QoxB; Belongs to the heme-copper respiratory oxidase family.
  
 0.989
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.
  
 0.984
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.
  
 
 0.982
ABC2559
Conserved hypothetical protein.
 
  
 0.922
qoxD
Cytochrome aa3 quinol oxidase subunit IV QoxD.
     
 0.903
qcrC
Menaquinol-cytochrome c reductase cytochrome b/c subunit; Component of the menaquinol-cytochrome c reductase complex.
  
  
 0.861
