Two examples of the application of single-wavelength anomalous dispersion (SAD) in macromolecular structure determination are described, both using the statistical phasing program SHARP. For the holmium-substituted calcium-binding protein psoriasin (22.7 kDa), a set of accurate phases has been obtained to a resolution of 1.05 A without recourse to an atomic model of the molecule. The accuracy of the phases resulted in an electron-density map of a quality comparable to sigma(A)-weighted 2mF(o… CONTINUE READING
