a, b View along the membrane normal from the stromal side (a) and along the membrane plan from the LHCI side (b). Protein subunits are shown as ribbon models and colored differently. c Pigment arrangement in the Fa PSI–LHCI supercomplex. Chls are shown as stick models in the same color as their interacting protein subunits in a, and carotenoids are shown as stick models in light blue. d Distribution of lipids in Fa PSI–LHCI. Five phosphatidyl glycerol molecules (PG, green), three monogalatosyl diglyceride molecules (MGDG, blue) and one digalactosyl diacylglycerol molecule (DGDG, magenta) are depicted as stick models. e, f Overlay of the Fa PSI–LHCI structure (PDB code 8WGH, red) with that of maize PSI–LHCI (Zm PSI–LHCI, PDB code 5ZJI, light blue), At PSI–LHCI (PDB code 8J7B, smudge) and pea PSI–LHCI (Ps PSI–LHCI, PDB code 4XK8, gray; 5L8R, tv_blue; 7DKZ, yellow) based on PsaA viewed along the membrane normal from the stromal side, with the protein structure and the chlorophyll arrangement shown in (e) and f, respectively. In c and f, the phytol chains of all Chls have been deleted for clarity.
