The 2.2 Å structure of the chromophore and pocket as Pfr derived from the mixed state SFX dataset (PDB code 9F4I, protomer B) is shown. Carbons, green. a q-weighted extrapolated electron density map of the chromophore contoured at 0.448 e- Å−3 (1.39 rmsd), α-facial view. The ethyl side chain of ring D shows electron density both α- and β-facially. b amino acids and waters (red spheres) surrounding the chromophore, α-facial view. PW, pyrrole water. H-bonds are shown as dashed yellow lines. c GAF domain molecular surface (orange) showing the chromophore pocket open to the medium.
