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

coxEHeme 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. (321 aa)    
Predicted Functional Partners:
coxB
Cytochrome c 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
coxA
Cytochrome c oxidase subunit I; 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.
 0.999
coxG
Possible cytochrome-c oxidase assembly protein; Exerts its effect at some terminal stage of cytochrome c oxidase synthesis, probably by being involved in the insertion of the copper B into subunit I; Belongs to the COX11/CtaG family.
 
 0.998
coxC
Cytochrome c oxidase subunit III.
 
 
 0.998
ctaA
Possible cytochrome c oxidase assembly protein; Catalyzes the oxidation of the C8 methyl side group on heme O porphyrin ring into a formyl group; Belongs to the COX15/CtaA family. Type 2 subfamily.
 
 0.998
norE
Putative denitrification protein NorE.
 
  
 0.957
hemZ
Ferrochelatase; Catalyzes the ferrous insertion into protoporphyrin IX. Belongs to the ferrochelatase family.
   
 
 0.932
ccoN,
Cytochrome-c oxidase fixN chain, heme and copper binding subunit; Belongs to the heme-copper respiratory oxidase family.
  
 
 0.925
ccoO,
Cytochrome-c oxidase fixO chain; Observed by proteomics; Citation: Proteomics from VerBerkmoes et al. (2003) unpublished.
  
 
 0.920
ccoP,
Cytochrome-c oxidase fixP chain; C-type cytochrome. Part of the cbb3-type cytochrome c oxidase complex.
  
 
 0.912
