ID 2.1.1.295 DE 2-methyl-6-phytyl-1,4-hydroquinone methyltransferase. AN 2-methyl-6-solanyl-1,4-hydroquinone methyltransferase. AN MPBQ/MSBQ methyltransferase. CA (1) S-adenosyl-L-methionine + 2-methyl-6-phytylbenzene-1,4-diol = CA S-adenosyl-L-homocysteine + 2,3-dimethyl-6-phytylbenzene-1,4-diol. CA (2) S-adenosyl-L-methionine + 2-methyl-6-all-trans-nonaprenylbenzene-1,4- CA diol = S-adenosyl-L-homocysteine + plastoquinol. CA (3) S-adenosyl-L-methionine + 6-geranylgeranyl-2-methylbenzene-1,4-diol = CA S-adenosyl-L-homocysteine + 6-geranylgeranyl-2,3-dimethylbenzene-1,4- CA diol. CC -!- Involved in the biosynthesis of plastoquinol, as well as vitamin CC E (tocopherols and tocotrienols).
