CO-CRYSTALS OF DEMETALLIZED CONCANAVALIN A WITH CADMIUM HAVING A CADMIUM ION BOUND IN BOTH THE S1 SITE AND THE S2 SITE
Overview
The crystal structures of cadmium/cadmium and zinc/calcium concanavalin A, (con A) at pH 5.0 and pH 6.15, respectively, were determined. The, structure of cadmium/cadmium con A confirms that the secondary, Cd(2+)-binding site S3 is empty at pH 5. The metal-binding sites S1 and S2, are only very slightly affected by the substitution with cadmium. On the, other hand, S1 and S2 and most of the protein surface of zinc/calcium con, A at pH 6.15 differ from other fully metal-bound and carbohydrate-free, structures. Most of these structural differences at the protein surface, are a result of the interplay between metal binding, protonation and, crystal packing. This interplay is expressed by relative rotations and, translations of the con A units in alternative crystal packings and, ... [(full description)]
