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

ctaAHeme-containing membrane protein CtaA; 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 1 subfamily. (302 aa)    
Predicted Functional Partners:
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.
 0.995
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).
 
 
 0.961
ypmQ
Conserved hypothetical YpmQ; Biological Process: electron transport.
 
 
 0.858
ctaD
Cytochrome caa3 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.
 
 
 0.802
ctaE
Cytochrome caa3 oxidase (subunit III).
 
 
 0.793
qoxB
Cytochrome aa3 quinol oxidase (subunit I); Belongs to the heme-copper respiratory oxidase family.
 
 
 0.746
ywfI
Chlorite dismutase; May function as heme-dependent peroxidase.
  
 
  0.745
cccA
Cytochrome c550.
 
 
 0.730
ctaG
CtaG.
 
   
 0.721
qoxC
Cytochrome aa3 quinol oxidase (subunit III).
 
 
 0.713
