An original hypothesis related the band to emission coming from pheophytin in reaction center of PSII. WebMar 1, 2013 · The major antenna of PSII, LHCII, is a trimeric light-harvesting complex (Lhc) composed of a combination of the Lhcb1–3 gene products. The minor Lhcbs consists of three monomers, Lhcb4–6, also named CP29, CP26 and CP24. All Lhcbs coordinate chlorophylls (Chls) a and b, and several xanthophylls [22]. change ink cartridge in hp officejet 4652
