Joint X-ray/neutron-refined structure of PGH–TIM with the 2mFo − DFc nuclear scattering-length density map contoured at 1.0σ and the mFo − DFc nuclear scattering-length difference density maps contoured at 3.0σ (green) and −3.0σ (red). (b–d) Nuclear scattering-length OMIT maps at 3.0σ of the D atoms of three important residues in the PGH–TIM active site: (b) His95, (c) Lys13 and (d) PGH (D2). |
