X-ray diffraction crystallography. A crystal of methanol dehydrogenase is bombarded with X-rays to determine its molecular structure. The dimensions of the crystal sample,visible here in the phial at centre,are usually only around 0.25 x 0.5 millimetres. The repeated pattern of the crystal lattice acts as a diffraction grating,diffracting the beam in a way which depends on the spacing and arrangement of atoms in the lattice. The scattered rays then strike a detector plate; the data is recorded either on X-ray sensitive photographic film,or with electronic equipment linked to a computer | |
