Lutein, a dihydroxy xanthophyll, is the most abundant carotenoid in plant photosynthetic tissues and plays crucial structural and functional roles in the light-harvesting complexes. Carotenoid beta-and epsilon-hydroxylases catalyze the formation of lutein from alpha-carotene (beta,epsilon-carotene). In contrast to the well studied beta-hydroxylases that have been cloned and characterized from many organisms, the epsilon-hydroxylase has only been genetically defined by the lut1 mutation in… CONTINUE READING
