Fig. 4: Comparison of the arrangement of LHCIs, Chls and other ligands among 4 LHCIs.
From: Structural study of monomeric and dimeric photosystem I-LHCI supercomplexes from a bryophyte
a Overall arrangement of 4 LHCIs from a view along the membrane plane and the stromal side. The square with dotted lines shows the differences at the N-terminus, squares with solid lines and dash-dotted lines show the differences at the AC loop, and square with dashed-line shows the differences at the BC loop. b Overall arrangement of Chls among 4 LHCIs viewed along the membrane plane, lumenal side and stromal side, respectively. The number of Chls is shown only when it has differences among the 4 LHCIs. c Overall arrangement of other ligands among 4 LHCIs viewed along the membrane plane, lumenal side and stromal side, respectively. Only ligands that had differences among the 4 LHCIs are labeled together with their numbers. CLA: chlorophyll a; CHL; chlorophyll b. BCR, β-carotene; LHG, dipalmitoylphosphatidyl glycerol; LUT, lutein. The color codes are the same as in Fig. 1. The comparison is based on the superposition of 4 LHCIs structures in the MpPSI-LHCIs monomer by MatchMaker in ChimeraX.
