“…In the green alga Chlamydomonas reinhardtii , the LHCI antenna, which contains nine different Lhca proteins (Lhca1–9) (Busch and Hippler, ), is organized as a double row, with the more internal one in a similar position as Lhca1–4 in plants. Besides these Lhca, the binding of an additional dimer was recently described next to PsaH, PsaI, and PsaB, that is the side of the core complex opposite to the LHCII binding site (Ozawa et al , ; Suga et al , ; Su et al , ). A similar organization was also described in the green alga Bryopsis corticulans (Qin et al , ) as well as in the red alga Cyanidioschyzon merolae (Pi et al , ), suggesting that the binding site of this additional dimer is conserved among several photosynthetic organisms.…”
