- 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 + H2O.
- CATALYTIC ACTIVITY: Antheraxanthin + ascorbate = zeaxanthin + dehydroascorbate + H2O.
- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane; Peripheral membrane protein; Lumenal side (By similarity).
- DEVELOPMENTAL STAGE: Low expression in young leaves, but high expression in older leaves.
- SIMILARITY: Belongs to the calycin superfamily. Lipocalin family.
