Fig. 3. (The S. elongatus chromophore models CYC1 (panels A-C), CYC2 (D-F) and CYC3 (G-I).
The top row shows the electron density around the chromophores. The middle row shows the S. elongatus chromophores (blue) projected normal to the rings and the bottom row shows the view in the edge projection.
