Fig. 4: Structures of the PSI-LHCI moiety and individual subunits in the PSI-LHCI-LHCII supercomplex of C. reinhardtii and their comparisons with those from the PSI-LHCI of red alga, green alga and the PSI-LHCI-LHCII of higher plant.

a Structural superposition of Cr-PSI-LHCI-LHCII (green) and two Cr-PSI-LHCI supercomplexes (PDB code 6JO5 and 6IJO, deep-salmon and marine) viewed from the stromal side. b–d Enlarged views of the Lhca2/Lhca9 subunits (b), PsaH subunits (c), and PsaL subunits (d) in a. e Structural comparison of the PsaH subunits from the PSI-LHCI-LHCII of green alga C. reinhardtii (green) and higher plant maize (PDB code 5ZJI, magenta). f, g Structural comparison of the PsaL subunits (f) and PsaO subunits (g) from the green alga C. reinhardtii (green), the red alga C. merolae (PDB code 5ZGB, cyan) and higher plant maize (PDB code 5ZJI, magenta). The newly discovered chlorophylls and carotenoids in e, f, and g are shown in bold sticks and spheres, respectively.
