Localization of the xanthophyll-cycle enzyme violaxanthin de-epoxidase within the thylakoid lumen and abolition of its mobility by a (light-dependent) pH decrease (in Spinacia oleracea)

The formation of zeaxanthin (Zea) from violaxanthin (Vio) in chloroplasts of leaves and algae upon strong illumination is currently suggested to play a role in the photoprotection of plants. Properties and location of the enzyme Vio de-epoxidase, which is responsible for the transformation of Vio to...
