Disease relevance of LHCB5

This hypothesis was confirmed by the analysis of two recombinant proteins obtained by overexpression of the Lhcb5 apoprotein in Escherichia coli and reconstitution in vitro with either violaxanthin or zeaxanthin [1].

High impact information on LHCB5

The same effect was observed in wild-type CP26 upon treatment that leads to the accumulation of zeaxanthin in the membrane and was interpreted as the consequence of a conformational change [1].
We conclude that CP29 and CP26 are unlikely to be sites for nonphotochemical quenching [2].
Antisense inhibition of the photosynthetic antenna proteins CP29 and CP26: implications for the mechanism of protective energy dissipation [2].
Membranes and supercomplexes lacking CP26 were less stable than those prepared from the wild type [3].
Alterations in the packing of the PSII complexes in the thylakoid membrane also resulted from the absence of CP26 [3].
