Putative chlorophyll-binding sites in RedCAPs, pdf file. Figure S2. Putative chlorophyll-binding sites in members of the LHC (light-harvesting complex) and the RedCAP protein families. Experimentally derived chlorophyll binding sites from Arabidopsis thaliana LHCII proteins are indicated in green according to [104-106]. Conserved amino acid positions that may represent putative binding sites for chlorophylls or carotenoids in RedCAPs are indicated in blue. Note that the second helix (helix II) is poorly conserved between distant members of the LHC protein family and not conserved between LHC and RedCAP, therefore the alignment of different helices II does not necessarily show homologous positions.
