Characterization of tocopherol cyclases from higher plants and cyanobacteria. Evolutionary implications for tocopherol synthesis and function.

Plant physiology - 1 Aug 2003

Sattler Scott E, Cahoon Edgar B, Coughlan Sean J, DellaPenna Dean

Abstract excerpt

Tocopherols are lipophilic antioxidants synthesized exclusively by photosynthetic organisms and collectively constitute vitamin E, an essential nutrient for both humans and animals. Tocopherol cyclase (TC) catalyzes the conversion of various phytyl quinol pathway intermediates to their correspond...
