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-methyltransferase; O-methyltransferase that catalyzes the 2 O-methylation steps in the ubiquinone biosynthetic pathway; Belongs to the methyltransferase superfamily. UbiG/COQ3 family. (240 aa)    
Predicted Functional Partners:
coq7
Hypothetical protein; Catalyzes the hydroxylation of 2-nonaprenyl-3-methyl-6- methoxy-1,4-benzoquinol during ubiquinone biosynthesis.
  
 0.978
EAQ63090.1
COG0654 2-polyprenyl-6-methoxyphenol hydroxylase and related FAD-dependent oxidoreductases.
 
 
 0.970
EAQ63089.1
Ubiquinone biosynthesis hydroxylase; COG0654 2-polyprenyl-6-methoxyphenol hydroxylase and related FAD-dependent oxidoreductases.
 
 
 0.964
EAQ65530.1
Hypothetical protein; COG0654 2-polyprenyl-6-methoxyphenol hydroxylase and related FAD-dependent oxidoreductases.
 
 
 0.895
ubiA
4-hydroxybenzoate polyprenyltransferase; 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.

COG1239 Mg-chelatase subunit ChlI.
  
 0.879
ubiE
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).
 
 0.834
ubiB
Hypothetical protein; Is probably a protein kinase regulator of UbiI activity which is involved in aerobic coenzyme Q (ubiquinone) biosynthesis.
  
 
 0.829
EAQ65822.1
Sarcosine oxidase, alpha subunit family protein; COG0446 Uncharacterized NAD(FAD)-dependent dehydrogenases; Belongs to the GcvT family.
  
 
 0.773
EAQ63720.1
Amino acid adenylation; COG1020 Non-ribosomal peptide synthetase modules and related proteins.
  
 0.756
