General annotation (Comments)

Function

Part of the xanthophyll (or violaxanthin) cycle for controlling the concentration of zeaxanthin in chloroplasts. Catalyzes the two-step mono de-epoxidation reaction. Stereospecific for all-trans xanthophylls. Zeaxanthin induces the dissipation of excitation energy in the chlorophyll of the light-harvesting protein complex of photosystem II.

Catalytic activity

Violaxanthin + ascorbate = antheraxanthin + dehydroascorbate + H(2)O.

Antheraxanthin + ascorbate = zeaxanthin + dehydroascorbate + H(2)O.

Enzyme regulation

Activity limitted by low ascorbate availability. Feedback inhibition by zeaxanthin. Requires the presence of micelle-forming lipids such as monogalactosyldiacylglyceride (MGDG). Low concentration of bilayer forming lipids, such as digalactosyldiacylglyceride (DGDG) or phosphatidylcholine, supports a slower but nearly complete activity.

Subcellular location

Plastidchloroplast thylakoid membrane; Peripheral membrane protein; Lumenal sideBy similarity.

Domain

The cysteine rich N-terminal region is required for activity.

Miscellaneous

The amount of VDE in vivo is estimated to be 1 molecule per 20-100 electron transport chains.

Sequence similarities

Belongs to the calycin superfamily. Lipocalin family.
