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. (307 aa)    
Predicted Functional Partners:
A1E_00865
COG1845 Heme/copper-type cytochrome/quinol oxidase, subunit 3.
 
 
 0.997
ctaA
Cytochrome c oxidase assembly protein; 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 2 subfamily.
  
 0.994
A1E_03360
Cytochrome c oxidase polypeptide 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.
 
 0.994
A1E_03350
Cytochrome c oxidase polypeptide 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).
 
 
 0.993
ctaG
Hypothetical protein; Exerts its effect at some terminal stage of cytochrome c oxidase synthesis, probably by being involved in the insertion of the copper B into subunit I; Belongs to the COX11/CtaG family.
 
 0.992
hemH
Ferrochelatase; Catalyzes the ferrous insertion into protoporphyrin IX. Belongs to the ferrochelatase family.
   
 
 0.938
A1E_01100
Excinuclease ABC subunit B.
 
 
 0.842
A1E_03505
Hypothetical protein.
  
 
 0.829
polA
DNA polymerase I; In addition to polymerase activity, this DNA polymerase exhibits 5'-3' exonuclease activity; Belongs to the DNA polymerase type-A family.
  
  
 0.736
nuoB
NADH dehydrogenase beta subunit; NDH-1 shuttles electrons from NADH, via FMN and iron-sulfur (Fe-S) centers, to quinones in the respiratory chain. Couples the redox reaction to proton translocation (for every two electrons transferred, four hydrogen ions are translocated across the cytoplasmic membrane), and thus conserves the redox energy in a proton gradient (By similarity).
