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 octaprenyltransferase (4-HB 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. (288 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.
    
 0.984
ubiD
3-octaprenyl-4-hydroxybenzoate carboxy-lyase (Polyprenyl p-hydroxybenzoate decarboxylase); Catalyzes the decarboxylation of 3-octaprenyl-4-hydroxy benzoate to 2-octaprenylphenol, an intermediate step in ubiquinone biosynthesis.
 
  
 0.951
ubiX
3-octaprenyl-4-hydroxybenzoate carboxy-lyase (polyprenyl p-hydroxybenzoate decarboxylase); 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.
 
  
 0.948
ispB
Octaprenyl-diphosphate synthase (octaprenyl pyrophosphate synthetase) (OPP synthetase); Belongs to the FPP/GGPP synthase family.
 
 
 0.887
ubiG
Ubiquinone biosynthesis O-methyltransferase; O-methyltransferase that catalyzes the 2 O-methylation steps in the ubiquinone biosynthetic pathway; Belongs to the methyltransferase superfamily. UbiG/COQ3 family.
 
 
 0.795
visC
Probable monooxygenase VisC.
  
   
 0.755
ubiF
2-octaprenyl-3-methyl-6-methoxy-1,4-benzoquinol hydroxylase UbiF.
  
   
 0.740
ubiH
2-octaprenyl-6-methoxyphenol hydroxylase.
  
   
 0.729
ubiE
Ubiquinone/menaquinone biosynthesis methyltransferase; 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).
 
   
 0.612
ubiB
Ubiquinone biosynthesis protein UbiB; Is probably a protein kinase regulator of UbiI activity which is involved in aerobic coenzyme Q (ubiquinone) biosynthesis.
  
 
 
 0.589
