Figure 9. Stereo drawing of the A. thaliana DHNA active site with electron density for the bound guanine and the water molecule. Residues that form hydrophobic or hydrogen bond interactions are shown. Ser52 and Tyr53 belong to the adjacent subunit. The final 2F[o] -F[c] electron density map covering the ligand and the water molecule is contoured at 1 sigma.
