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 subunit IV; COG3125 Heme/copper-type cytochrome/quinol oxidase, subunit 4. (114 aa)    
Predicted Functional Partners:
ctaE
Cytochrome caa3 subunit III; COG1845 Heme/copper-type cytochrome/quinol oxidase, subunit 3.
 
 0.999
ctaD
Cytochrome caa3 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
ctaC
Cytochrome caa3 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
ctaB
Heme O synthase, protoheme IX farnesyltransferase; Converts protoheme IX and farnesyl diphosphate to heme O. Belongs to the UbiA prenyltransferase family.
  
 
 0.993
qcrA
Menaquinol-cytochrome c reductase (iron-sulfur subunit); COG0723 Rieske Fe-S protein.
  
 
 0.942
qcrC
Menaquinol-cytochrome c reductase cytochrome b/c subunit; Component of the menaquinol-cytochrome c reductase complex.
  
  
 0.924
ADC48508.1
CtaG-like assemby protein; COG3336 Predicted membrane protein.
 
  
 0.919
cccA
COG2010 Cytochrome c, mono- and diheme variants.
  
  
 0.895
ADC49161.1
COG2010 Cytochrome c, mono- and diheme variants.
