4YOP: CRYSTAL STRUCTURE OF HEN EGG-WHITE LYSOZYME
Acta Crystallogr. D Biol. Crystallogr. (2015) 71 p.2519-2525
Serial femtosecond crystallography (SFX) allows structures to be determined with minimal radiation damage. However, phasing native crystals in SFX is not very common. Here, the structure determination of native lysozyme from single-wavelength anomalous diffraction (SAD) by utilizing the anomalous signal of sulfur and chlorine at a wavelength of 1.77 A is successfully demonstrated. This sulfur SAD method can be applied to a wide range of proteins, which will improve the determination of native crystal structures.
