The tocopherol, tocotrienol, and plastoquinone biosynthetic pathway in plants

The tocopherol, tocotrienol, and plastoquinone biosynthetic pathway in plants. This figure represents the enzymatic reactions and intermediates that are involved in the biosynthesis of tocopherol, tocotrienol, and plastoquinone. Arabidopsis mutants of the corresponding pathway genes are given in parentheses behind the enzymes. DMPBQ, 2,3-dimethyl-5-phytyl-1,4-benzoquinone; HPP, p-hydroxyphenylpyruvate; MSBQ, 2-methyl-6-solanesyl-1,4-benzoquinone; phytyl-DP, phytyl-diphosphate; solanesyl-DP, solanesyl diphosphate; HPPD, HPP dioxygenase; HST, homogentisate solanesyltransferase; MPBQMT (vte3), MPBQ/MSBQ methyltransferase; PK (vte5), phytol kinase; PPK, phytyl phosphate kinase.
