The role of red forms in excitation energy localization. Chl molecules of the structure from [41], deposited in the Protein Data Bank under accession number 1qzv, are shown. Core complex, antenna and linker chlorophylls are shown respectively in blue, dark and light green. The special pair P700 is highlighted in purple. Chls in sites 603 and 609 of antenna polypeptides are evidenced as well: they are in red in the case of Lhca3 and Lhca4, in orange for Lhca1 and Lhca2, according to their fluorescence emission properties [52].
