Tocopherols protect Synechocystis sp. strain PCC 6803 from lipid peroxidation.

Plant physiology - 1 Jul 2005

Maeda Hiroshi, Sakuragi Yumiko, Bryant Donald A, Dellapenna Dean

Abstract excerpt

Tocopherols (vitamin E) are lipid-soluble antioxidants synthesized only by photosynthetic eukaryotes and some cyanobacteria, and have been assumed to play important roles in protecting photosynthetic membranes from oxidative stress. To test this hypothesis, tocopherol-deficient mutants of Synecho...
