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

ctaBHeme 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. (442 aa)    
Predicted Functional Partners:
coxC
Cytochrome c oxidase subunit III; CoxC.
 
 
 0.996
coxB1
Cytochrome c oxidase subunit II; CoxB1.
 
 
 0.996
coxA2
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.
 
 0.993
coxA1
Cytochrome c oxidase subunit I; CoxA1; Belongs to the heme-copper respiratory oxidase family.
 
 0.986
coxB2
Cytochrome c oxidase subunit II; CoxB2.
  
 
 0.971
pqqE
Coenzyme PQQ synthesis protein; PqqE.
  
  
  0.913
ccp
Cytochrome aa3 controlling protein; Ccp.
  
  
 
0.904
aspB2
Aspartate aminotransferase; AspB2.
   
 
 0.809
trp4
ABC transporter, ATP-binding protein homolog; Trp4.
  
    0.805
nolC
NADH dehydrogenase/oxidoreductase-like protein; NolC.
   
  
 0.774
