Annotated sequence alignments, pdf file. Figure S1. (A) Sequence alignment of helices I and III of RedCAPs with red lineage LHCF, CAC/LHCR and LHCX/LI818 proteins. (B) Sequence alignment of helices I and III of RedCAPs with green lineage CAB (LHCa, LHCb and LHCP), LHCSR/LI818, ELIP and LHL4 proteins. (C) Full-length sequence alignment of identified RedCAP amino acid sequences. Identical amino acids are surrounded by black and similar amino acids by grey boxes. Chl-binding motifs located in transmembrane helices I and III are marked with a green bar above the alignment, and the approximate position of transmembrane helix II is marked with a grey bar. Accession numbers of aligned sequences are given in Table S1 (see Additional file 1).
