Stabilization and Binding of [V 4 O 12 ] 4- and Unprecedented [V 20 O 54 (NO 3 )] n- to Lysozyme upon Loss of Ligands and Oxidation of the Potential Drug V IV O(acetylacetonato) 2.

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