Abstract

The application of the neutron-diffraction technique, which assigns H-atom positions in proteins and differentiates between H and D atoms, has been mainly focused on structural issues in three research areas: protein reaction mechanisms; protein dynamics; and protein–water interactions. Topics covered in this chapter include: diffraction geometries; the information content of neutron density maps; phasing models and evaluation of correctness; methodologies employed to refine neutron data; and D2O − H2O difference maps and their applications.

Keywords:

  • D2O − H2O difference maps;
  • hydrogen/deuterium exchange;
  • neutron density maps;
  • neutron diffraction;
  • phasing;
  • quasi-Laue neutron diffraction;
  • refinement;
  • solvent structure;
  • water molecules
