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

ctaECYTOCHROME C OXIDASE SUBUNIT 3. (205 aa)    
Predicted Functional Partners:
ctaB
Polyprenyltransferase (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.
 
 
 0.999
qcrB
CYTOCHROME B, MEMBRANE PROTEIN; Cytochrome b subunit of the cytochrome bc1 complex, an essential component of the respiratory electron transport chain required for ATP synthesis. The bc1 complex catalyzes the oxidation of menaquinol and the reduction of cytochrome c in the respiratory chain. The bc1 complex operates through a Q-cycle mechanism that couples electron transfer to generation of the proton gradient that drives ATP synthesis.
 
 0.999
qcrA1
RIESKE IRON-SULFUR PROTEIN; Iron-sulfur subunit of the cytochrome bc1 complex, an essential component of the respiratory electron transport chain required for ATP synthesis. The bc1 complex catalyzes the oxidation of menaquinol and the reduction of cytochrome c in the respiratory chain. The bc1 complex operates through a Q-cycle mechanism that couples electron transfer to generation of the proton gradient that drives ATP synthesis.
 
 0.999
qcrC
CYTOCHROME C1; Cytochrome c1 subunit of the cytochrome bc1 complex, an essential component of the respiratory electron transport chain required for ATP synthesis. The bc1 complex catalyzes the oxidation of menaquinol and the reduction of cytochrome c in the respiratory chain. The bc1 complex operates through a Q-cycle mechanism that couples electron transfer to generation of the proton gradient that drives ATP synthesis.
 
 0.999
ctaF
Putative membrane protein; Part of cytochrome c oxidase, its function is unknown; Belongs to the cytochrome c oxidase bacterial subunit CtaF family.
 
 0.999
ctaC
CYTOCHROME C OXIDASE CHAIN 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) (By similarity).
 
 0.999
ctaD
PROBABLE CYTOCHROME C OXIDASE POLYPEPTIDE SUBUNIT; 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 (By similarity).

Cgl2017
Putative membrane protein.
   
   0.993
atpB
ATP SYNTHASE F0 SUBUNIT 6; Key component of the proton channel; it plays a direct role in the translocation of protons across the membrane.
   
 
 0.956
Cgl0818
Conserved hypothetical protein.
   
   0.900
