Structural Studies on Protein Macromolecules by the X-Ray/Synchrotron Radiation and Neutron Protein Crystallography

Abstract

Crystal structure analysis is a most powerful technique to clarify the relationship between threedimensional structure and functions by the terms of atomic resolution. Especially, since biological important materials are composed from some light atoms (C, O and H), neutron diffraction method is available for a determination of them rather than the X-ray source. In this section, there is an introduction of X-ray and neutron protein crystallography and an analysis of human hemoglobin.
