Efficient determination of protein crystal structures requires automated, x-ray data analysis. Here, we describe the expert system ELVES and its use, to determine automatically the structure of a 12-kDa protein., Multiwavelength anomalous diffraction analysis of a selenomethionyl, derivative was used to image the Asn-16-Ala variant of the GCN4 leucine, zipper. In contrast to the parallel, dimeric coiled coil formed by the WT, sequence, the mutant unexpectedly formed an antiparallel trimer. This, structural switch reveals how avoidance of core cavities at a single site, can select the native fold of a protein. All structure calculations, including indexing, data processing, locating heavy atoms, phasing by, multiwavelength anomalous diffraction, model building, and refinement, were completed without human intervention. The results demonstrate the, feasibility of automated methods for determining high-resolution, x-ray, crystal structures of proteins.
