Antenna–antenna and antenna–core interactions in the C2S2M2N2-type PSII–LHCII supercomplex of C. reinhardtii. (A) Surface and cartoon representations of the local structure including LHCII (S-LHCII, M-LHCII, and N-LHCII), CP26, CP29, D1, D2, CP43, CP47, PsbH, PsbI, PsbX, PsbW, and PsbZ, viewed from the stromal side. (B) Interactions between S′-LHCII (monomer 1) and CP26′. The closed interactions between S′-LHCII (monomer 1) and the extra stromal as well as luminal loops of CP26′ are highlighted with solid boxes. (C) Interactions between N-LHCII (monomer 3) and D2 mediated by PsbX. (D) Interactions between N-LHCII (monomer 1) and CP47. (E) Interactions between M-LHCII (monomer 3) and CP29. (F) Interactions between N-LHCII (monomer 1) and CP29.
