Violaxanthin inhibits nonphotochemical quenching in light-harvesting antenna of Chromera velia.
Kaňa R, Kotabová E, Kopečná J, Trsková E, Belgio E, Sobotka R, Ruban AV. Kaňa R, et al. FEBS Lett. 2016 Apr;590(8):1076-85. doi: 10.1002/1873-3468.12130. Epub 2016 Apr 4. FEBS Lett. 2016. PMID: 26988983 Free article.
NPQ is triggered by chloroplast thylakoid lumen acidification and is accompanied by violaxanthin de-epoxidation to zeaxanthin, which further stimulates NPQ. In the present study, we show that violaxanthin can act in the opposite direction to zeaxanthin because an in …

Violaxanthin and Zeaxanthin May Replace Lutein at the L1 Site of LHCII, Conserving the Interactions with Surrounding Chlorophylls and the Capability of Triplet-Triplet Energy Transfer.
Carbonera D, Agostini A, Bortolus M, Dall'Osto L, Bassi R. Carbonera D, et al. Int J Mol Sci. 2022 Apr 27;23(9):4812. doi: 10.3390/ijms23094812. Int J Mol Sci. 2022. PMID: 35563202 Free PMC article.
In this work, we investigated the effects on this quenching induced in LHCII by the replacement of the lutein bound at the L1 site with violaxanthin and zeaxanthin. We studied LHCII isolated from the Arabidopsis thaliana mutants lut2-in which lutein is replaced by viola …
