geranylgeranyl diphosphate + homogentisate | Hordeum vulgare | the enzyme is involved in the biosynthesis of the vitamin E, tocotrienols. It uses primarily geranylgeranyl diphosphate as a substrate, but is capable of generating the 2-methyl-6-phytylbenzoquinol precursor of tocopherols, particularly in the presence of elevated ratios of phytyl diphosphate:geranylgeranyl diphosphate | diphosphate + 6-geranylgeranyl-2-methylbenzene-1,4-diol + CO2 | - |

geranylgeranyl diphosphate + homogentisate | Hordeum vulgare cv. Morex | the enzyme is involved in the biosynthesis of the vitamin E, tocotrienols. It uses primarily geranylgeranyl diphosphate as a substrate, but is capable of generating the 2-methyl-6-phytylbenzoquinol precursor of tocopherols, particularly in the presence of elevated ratios of phytyl diphosphate:geranylgeranyl diphosphate | diphosphate + 6-geranylgeranyl-2-methylbenzene-1,4-diol + CO2 | - |
