STRUCTURAL EFFECTS OF MONOVALENT ANIONS ON POLYMORPHIC LYSOZYME CRYSTALS
OverviewOverview
Understanding direct salt effects on protein crystal polymorphism is, addressed by comparing different crystal forms (triclinic, monoclinic, tetragonal and orthorhombic) for hen, turkey, bob white quail and human, lysozymes. Four new structures of hen egg-white lysozyme are reported:, crystals grown in the presence of NapTS diffracted to 1.85 A, of NaI to, 1.6 A, of NaNO(3) to 1.45 A and of KSCN to 1.63 A. These new structures, are compared with previously published structures in order to draw a, mapping of the surface of different lysozymes interacting with monovalent, anions, such as nitrate, chloride, iodide, bromide and thiocyanate. An, analysis of the structural sites of these anions in the various lysozyme, structures is presented. This study shows common anion sites whatever the, ... [(full description)]
