RIKEN team achieves continuous femtosecond high-resolution crystal structure analysis (SFX) of proteins

In the procedure, developed at RIKKEN’s SPring8 radiation facilities, microcrystals of proteins are mixed into hyaluronic acid as a hydrogel transport medium, and 20.000 to 30.000 high-resolution diffraction patterns are obtained by femtosecond laser irradiation from which the protein structures can be calculated at about 2 A resolution or better. The procedure is expected to allow structure elucidation of proteins from which crystals are difficult to grow, e. g. for membrane proteins important for drug design.
