The two binding sites on the His15 residue of hen egg-white lysozyme (HEWL). The Fo − Fc OMIT electron-density maps are shown in green and the anomalous difference electron-density maps are shown in orange at a 3σ cutoff: 4dd7 (Tanley, Diederichs et al., 2013a) processed by (a) XDS (Kabsch, 2010) and (b) EVAL (Schreurs et al., 2010). |
