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

ctaBProtoheme IX farnesyltransferase; 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. (333 aa)    
Predicted Functional Partners:
ABB49504.1
Cytochrome c oxidase, subunit III; Alternative locus ID: P9312_04681.
 
 
 0.998
ABB49505.1
Cytochrome-c oxidase; 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.
 
 0.998
ABB49506.1
Putative cytochrome c oxidase, subunit 2; 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).
 
 
 0.998
ABB49507.1
Cytochrome c oxidase subunit XV assembly protein; Alternative locus ID: P9312_04711.
 
 0.998
hemH
Ferrochelatase; Catalyzes the ferrous insertion into protoporphyrin IX. Belongs to the ferrochelatase family.
   
 
 0.936
ABB50747.1
Heme oxygenase (decyclizing); Alternative locus ID: P9312_18371.
     
  0.900
ABB49509.1
ATPase; Alternative locus ID: P9312_04731.
       0.727
ABB49510.1
Putative multidrug efflux ABC transporter; Alternative locus ID: P9312_04741.
       0.648
