Fig. 2 — Models of (B)Chls in the B800 site of Rbs. acidophilus LH2 (PDB ID: 1NKZ) [14]. The polypeptides are shown in surface representation with positive charges in blue, negative in red and uncharged regions in white. Cofactors are in stick representation with B850 in grey and carotenoid in yellow. The B800 BChl a has been coloured cyan (Panel A). Models of LH2 containing BChl b (Panel B), 3-acetyl Chl a (Panel C), Chl d (panel D), Chl a (Panel E), and Chl f (Panel F) in the B800 site are also shown. Below each structure are 2D representations of the A and B rings of each (B)Chl with rings A, B and carbons 1–9 labelled.
