In enzymology, a hexaprenyldihydroxybenzoate methyltransferase (EC 2.1.1.114) is an enzyme that catalyzes the chemical reaction
- S-adenosyl-L-methionine + 3-hexaprenyl-4,5-dihydroxybenzoate S-adenosyl-L-homocysteine + 3-hexaprenyl-4-hydroxy-5-methoxybenzoate
Thus, the two substrates of this enzyme are S-adenosyl methionine and 3-hexaprenyl-4,5-dihydroxybenzoate, whereas its two products are S-adenosylhomocysteine and 3-hexaprenyl-4-hydroxy-5-methoxybenzoate.
This enzyme belongs to the family of transferases, specifically those transferring one-carbon group methyltransferases. The systematic name of this enzyme class is S-adenosyl-L-methionine:3-hexaprenyl-4,5-dihydroxylate O-methyltransferase. Other names in common use include 3,4-dihydroxy-5-hexaprenylbenzoate methyltransferase, and dihydroxyhexaprenylbenzoate methyltransferase. This enzyme participates in ubiquinone biosynthesis.
