antheraxanthin + ascorbate | Solanum lycopersicum | de-epoxidation reaction of the xanthophyll cycle plays an important role in the protection of the chloroplast against photooxidative damage. Violaxanthin is bound to the antenna proteins of both photosystems. In photosystem II, the formation of zeaxanthin is essential for the pH-dependent dissipation of excess light energy as heat. Violaxanthin bound to site V1 and N1 is easily accessible for de-epoxidation, whereas violaxanthin bound to L2 is only partially and/or with the slower kinetics converible to zeaxanthin | zeaxanthin + dehydroascorbate + H2O | - |
