An approach to solving the [[phase problem]] in protein [[structure determination]] by comparing structure factors collected at different wavelengths, usually from a tunable X-ray synchrotron source, including the absorption edge of a heavy-atom scatterer. Also known as '''multiple-wavelength anomalous diffraction''' or '''multiwavelength anomalous dispersion'''.

Diffraction anomale multilongueurs d'ondes (Fr). Diffrazione anomala a più lunghezze d'onda (It)

Definition

An approach to solving the phase problem in protein structure determination by comparing structure factors collected at different wavelengths, usually from a tunable X-ray synchrotron source, including the absorption edge of a heavy-atom scatterer. Also known as multiple-wavelength anomalous diffraction or multiwavelength anomalous dispersion.

History

This technique was introduced by W. Hendrickson (Hendrickson, W. A., 1991, Determination of macromolecular structures from anomalous diffraction of synchrotron radiation. Science, 254, 51–58.)
