MIRAS STRUCTURE DETERMINATION FROM HEMIHEDRALLY TWINNED CRYSTALS
Overview
The structure of Rna1p was originally solved to 2.7 A resolution by MIRAS, from crystals with partial hemihedral twinning in space group I4(1), [Hillig et al. (1999), Mol. Cell, 3, 781-791] by finding a low-twinned, native crystal (twin fraction alpha=0.06) and after twin correction of all, data sets. Rna1p crystals have now been used to examine how far twinning, and twin correction affect MIR phasing with a higher resolution but highly, twinned native data set. Even high hemihedral twinning [alphanative=0.39, alphaderivative=0.24] would not have hindered heavy-atom site, identification of strong derivatives using difference Patterson maps., However, a weaker derivative could have been missed and refinement would, have stalled at high R values had twinning not been identified and, ...
