    Coiled coils are ubiquitous protein-protein interaction motifs found in many eukaryotic proteins. The elongated, flexible and often irregular natureof coiled coils together with their tendency to form fibrous arrangements in crystals impose challenges on solving the phase problem by molecular replacement. Here, we report the successful combinatorial use of native- and rational engineered disulfide bridges together with sulfur-SAD phasing as a powerful tool to stabilize and solve the structure of coiled-coil domains in a straightforward manner. Our study is a key example of how modern sulfur SAD combined with mutagenesis can help to advance and simplify the structural study of challenging coiled-coil domains by X-ray crystallography.
