High-resolution crystal structures of lysozyme in the presence of the potential drug V IV O(acetylacetonato) 2 under two different experimental conditions have been solved. The crystallographic study reveals the loss of the ligands, the oxidation of V IV to V V and the subsequent formation of adducts of the protein with two different polyoxidovanadates: [V 4 O 12 ] 4- , which interacts with lysozyme non-covalently, and the unprecedented [V 20 O 54 (NO 3 )] n- , which is covalenty bound to the side chain of an aspartate residue of symmetry related molecules.
