WebLECTURE 4. Crystallography . Crystallography For electromagnetic radiation to be diffracted the spacing in the grating should be of the same order as the wavelength In crystals the typical interatomic spacing ~ 2-3 Å so the suitable radiation is X-rays Hence, x-rays can be used for the study of • Crystallography gives you a static snapshot of a protein’s structure – Usually (but not always) this snapshot corresponds to the protein’s “average” structure 12 For example, you can compare structures determined by crystallography to structures determined by NMR or electron microscopy.
