Figure 6
Conserved residues near the copper center. (a) Fo − Fc neutron scattering-length density omit map for the hydroxy group of Tyr164 in purple contoured at 3.0σ. The hydrogen bond between Tyr164 and Gln162 OE1 is represented by a black dashed line. (b) Fo − Fc neutron scattering-length density omit map for His147 in purple contoured at 3.0σ, indicating that His147 is singly protonated at the NE2 position. |
