a Structure of Fa Lhca3 showing the extent of surface hydrophobicity. The degree of hydrophobicity is shown from white (no hydrophobicity) to red (high hydrophobicity). The black dashed boxes indicate three regions (I, II and III) surrounding Chl a303 and Chl a309, with different amino acid residues between Fa Lhca3, pea (Pisum sativum, Ps) Lhca3 and maize (Zea mays, Zm) Lhca3. b Enlarged views of boxed areas I–III) in Fa Lhca3 and the structure of the corresponding area in Ps Lhca3 and Zm Lhca3. c Sequence alignment of regions I–III from Fa Lhca3, Ps Lhca3 and Zm Lhca3. Color codes: Chl a303 and Chls a309, green; other Chl molecules, purple. PDB codes: Fa PSI–LHCI, 8WGH; Ps Lhca3, 4XK8; Zm Lhca3, 5ZJI.
