Figure 2
The active site of copper nitrite reductase (PDB entry 6gtj, perdeuterated; Halsted et al., 2019  ). (a) A D2O molecule is bound to the active site with a neutral His256 (HisCAT). 2Fo − Fc NSLD map (σ = 1.00) is displayed as a blue mesh; H and D atoms are displayed in white and turquoise, respectively. (b) An OD− ion is bound to the active site with a positively charged His211 (HisCAT; PDB entry 6l46, H/D exchanged; Fukuda et al., 2020). NSLD 2Fo − Fc density (σ = 1.50) is displayed as a blue mesh; H and D atoms are displayed in white and turquoise, respectively. |
