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

ubiA4-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. (294 aa)    
Predicted Functional Partners:
ubiC
Chorismate--pyruvate lyase; Removes the pyruvyl group from chorismate, with concomitant aromatization of the ring, to provide 4-hydroxybenzoate (4HB) for the ubiquinone pathway.
    
 0.995
ubiD
3-octaprenyl-4-hydroxybenzoate carboxy-lyase; Catalyzes the decarboxylation of 3-octaprenyl-4-hydroxy benzoate to 2-octaprenylphenol, an intermediate step in ubiquinone biosynthesis.
 
  
 0.986
ubiX
3-octaprenyl-4-hydroxybenzoate carboxy-lyase; Flavin prenyltransferase that catalyzes the synthesis of the prenylated FMN cofactor (prenyl-FMN) for 4-hydroxy-3-polyprenylbenzoic acid decarboxylase UbiD. The prenyltransferase is metal-independent and links a dimethylallyl moiety from dimethylallyl monophosphate (DMAP) to the flavin N5 and C6 atoms of FMN; Belongs to the UbiX/PAD1 family.
 
  
 0.984
BG55_09650
Octaprenyl diphosphate synthase; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the FPP/GGPP synthase family.
 
 
 0.971
ubiG
3-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.
 
 0.848
ubiE
Ubiquinone 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).

 0.745
BG55_15140
2-octaprenyl-6-methoxyphenyl hydroxylase; Oxygenase that introduces the hydroxyl group at carbon four of 2-octaprenyl-6-methoxyphenol resulting in the formation of 2-octaprenyl-6-methoxy-1,4-benzoquinone; Derived by automated computational analysis using gene prediction method: Protein Homology.
  
   
 0.744
BG55_16165
Hypothetical protein; Derived by automated computational analysis using gene prediction method: Protein Homology.
    
 0.721
ubiF
2-octaprenyl-3-methyl-6-methoxy-1,4-benzoquinol hydroxylase; Catalyzes the formation of 2-octaprenyl-3-methyl-5-hydroxy-6-methoxy-1,4-benzoquinol from 2-octaprenyl-3-methyl-6-methoxy-1,4-benzoquinol; functions in the biosynthesis of ubiquinone or coenzyme Q; Derived by automated computational analysis using gene prediction method: Protein Homology.
