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

ubiG3-demethylubiquinone-9 3-O-methyltransferase; O-methyltransferase that catalyzes the 2 O-methylation steps in the ubiquinone biosynthetic pathway; Belongs to the methyltransferase superfamily. UbiG/COQ3 family. (248 aa)    
Predicted Functional Partners:
CCQ75423.1
Putative 2-polyprenyl-6-methoxyphenol 4-hydroxylase[Include FAD dependent oxidoreductase domain]; Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative enzyme.
 
 
 0.975
coq7
Putative Ubiquinone biosynthesis protein COQ7 homolog; Catalyzes the hydroxylation of 2-nonaprenyl-3-methyl-6- methoxy-1,4-benzoquinol during ubiquinone biosynthesis.
  
 0.946
CCQ73940.1
Homologs of previously reported genes of unknown function.
  
  
  0.911
rpiB
Ribose-5-phosphate isomerase B; Function of strongly homologous gene; enzyme.
      0.907
CCQ74880.1
Uncharacterized protein; Homologs of previously reported genes of unknown function.
     
  0.900
ubiA
Putative 4-hydroxybenzoate-octaprenyl transferase; Catalyzes the prenylation of para-hydroxybenzoate (PHB) with an all-trans polyprenyl group. Mediates the second step in the final reaction sequence of ubiquinone-8 (UQ-8) biosynthesis, which is the condensation of the polyisoprenoid side chain with PHB, generating the first membrane-bound Q intermediate 3-octaprenyl-4-hydroxybenzoate.

CCQ73184.1
Putative quinone oxidoreductase yhdH; Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative enzyme.
  
    0.774
ubiB
Ubiquinone biosynthesis protein ubiB; Is probably a protein kinase regulator of UbiI activity which is involved in aerobic coenzyme Q (ubiquinone) biosynthesis. Belongs to the ABC1 family. UbiB subfamily.
  
 0.715
ubiE-2
Ubiquinone/menaquinone biosynthesis methyltransferase ubiE; Methyltransferase required for the conversion of demethylmenaquinol (DMKH2) to menaquinol (MKH2) and the conversion of 2-polyprenyl-6-methoxy-1,4-benzoquinol (DDMQH2) to 2-polyprenyl-3- methyl-6-methoxy-1,4-benzoquinol (DMQH2).
  
 
 0.689
