The 6.5 kDa PSII subunit PsbZ (ycf9 in Chlamydomonas) is coded by an open reading frame that is ubiquitously present in chloroplast and cyanobacterial genomes. PsbZ seems to control the interaction of PSII cores with the light-harvesting antenna involving changes in protein phosphorylation within PSII units, the deepoxidation state of xanthophylls, and the kinetics and amplitude of nonphotochemical quenching (NPQ).

免疫原
KLH-conjugated synthetic peptide derived from PsbZ protein sequence of Arabidopsis thaliana (AtCg00300). This sequence is highly conserved in dicots, monocots, and Physcomitrella patens but only weakly in Chlamydomonas reinhardtii.
