Identification
HMDB Protein ID HMDBP03700
Secondary Accession Numbers
  • 9288
Name 4-hydroxybenzoate polyprenyltransferase, mitochondrial
Synonyms
  1. COQ2 homolog
  2. PHB:polyprenyltransferase
  3. hCOQ2
  4. Para-hydroxybenzoate--polyprenyltransferase
Gene Name COQ2
Protein Type Enzyme
Biological Properties
General Function Involved in prenyltransferase activity
Specific Function Catalyzes the prenylation of para-hydroxybenzoate (PHB) with an all-trans polyprenyl group. Mediates the second step in the final reaction sequence of coenzyme Q (CoQ) biosynthesis, which is the condensation of the polyisoprenoid side chain with PHB.
Pathways
  • Ubiquinone and other terpenoid-quinone biosynthesis
  • ubiquinone biosynthesis
  • Ubiquinone Biosynthesis
