Function

function

Involved in the synthesis of both tocopherols and tocotrienols (vitamin E), which presumably protect photosynthetic complexes from oxidative stress. Catalyzes the conversion of 2-methyl-6-phytyl-1,4-hydroquinone and 2,3-dimethyl-5-phytyl-1,4-hydroquinone (DMPQ) to delta- and gamma-tocopherol respectively. Converts also 2,3-dimethyl-5-geranylgeranyl-1,4-hydroquinone (DMGQ) to gamma-tocotrienol.

Catalytic activity

Pathway

Cofactor biosynthesis; tocopherol biosynthesis.
