Title: Occupancy and functional architecture of the pigment binding sites of photosystem II antenna complex Lhcb5.
Photosynthesis was affected in plants lacking CP24 but not in plants lacking CP26: CP24 mutant had decreased electron transport rates, lower DeltapH gradient across the grana membranes, reduced capacity for nonphotochemical quenching, and limited growth

Analysis of the xanthophyll binding LHC proteins showed that the Lhcb5 photosystem II subunit (also called CP26) undergoes a change in its pI upon binding of zeaxanthin.
Title: A mechanism of nonphotochemical energy dissipation, independent from PsbS, revealed by a conformational change in the antenna protein CP26.
