- •
LHCII in the lipid phase forms structures characterized by 77 K fluorescence emission band at 715 nm.
- •
Violaxanthin promotes trimeric organization of LHCII.
- •
Zeaxanthin promotes monomerization of LHCII.
- •
In the presence of violaxanthin, LHCII forms supramolecular structures characterized by low rate of excitation quenching.
