ENZYME entry: EC 2.5.1.115

Accepted Name
Homogentisate phytyltransferase.
Alternative Name(s)
HPT.
Reaction catalysed
Phytyl diphosphate + homogentisate <=> diphosphate + 2-methyl-6-phytylbenzene-1,4-diol + CO(2)
Cofactor(s)
Mg(2+).
Comment(s)
  • Involved in the biosynthesis of the vitamin E tocopherols.
  • While the enzyme from the cyanobacterium Synechocystis PCC 6803 has an appreciable activity with geranylgeranyl diphosphate (EC 2.5.1.116), the enzyme from the plant Arabidopsis thaliana has only a low activity with that substrate.
  • Formerly EC 2.5.1.n8.
