An ab initio method is described for solving protein structures for which atomic resolution (better than 1.2 A) data are available. The problem is divided into two stages.

Article Synopsis
- The structure of rusticyanin, a protein with a molecular weight of 16.8 kDa, has recently been determined using direct methods and single-wavelength anomalous scattering (SAS).
- A comparison was made between results obtained from the Sim distribution approach and the CCP4 procedure MLPHARE against direct methods.
- The analysis revealed that direct methods provided significantly better phase accuracy and improved electron-density maps, with an average phase error of 56 degrees compared to around 63 degrees for the other approaches.
