Fig. 6: Multiple alignment of helix B sequences of LHC proteins with simplified phylogenetic tree topology on the right.
From: Eustigmatophyte model of red-shifted chlorophyll a absorption in light-harvesting complexes
Highlighted is the Chl-binding site i = a403/a603 (H or N) and the corresponding position at i-4 (see text for explanation). Detailed version of the phylogenetic tree used to classify the proteins into groups given on the left is presented in Supplementary Fig. S5. Sequences of proteins that have been purified in a red-shifted Chl a-containing form are shown in red.
