In enzymology, a 4-hydroxybenzoate polyprenyltransferase (EC 2.5.1.39) is an enzyme that catalyzes the chemical reaction
- a polyprenyl diphosphate + 4-hydroxybenzoate [math]\displaystyle{ \rightleftharpoons }[/math] diphosphate + a 4-hydroxy-3-polyprenylbenzoate
Thus, the two substrates of this enzyme are a polyprenyl diphosphate and 4-hydroxybenzoate, whereas its two products are diphosphate and 4-hydroxy-3-polyprenylbenzoate.
This enzyme belongs to the family of transferases, specifically those transferring aryl or alkyl groups other than methyl groups. This enzyme participates in ubiquinone biosynthesis.[1]
Nomenclature
The systematic name of this enzyme class is polyprenyl-diphosphate:4-hydroxybenzoate polyprenyltransferase. Other names in common use include:
- nonaprenyl-4-hydroxybenzoate transferase,
- 4-hydroxybenzoate transferase,
- p-hydroxybenzoate dimethylallyltransferase,
- p-hydroxybenzoate polyprenyltransferase,
- p-hydroxybenzoic acid-polyprenyl transferase,
- p-hydroxybenzoic-polyprenyl transferase, and
- 4-hydroxybenzoate nonaprenyltransferase
