Crystallized proteins
WebFeb 20, 2013 · The vast majority of substrate binding proteins have been crystallized in the closed- ligand bound conformation (for a detailed list see [ 2 ]). This is mainly due to the fact that the substrate bound protein adopts a stable conformation and possesses a drastically reduced intrinsic flexibility. WebProtein Crystals Gale Rhodes, in Crystallography Made Crystal Clear (Third Edition), 2006 Publisher Summary X-ray crystallography is used to examine a sample that is in the crystalline state. Crystals of many proteins and other biomoleculars have been obtained and analyzed in the X-ray beam.
