Herein, we report several resolved crystal structures of lysozyme with bound V(IV) O(2+) and V(IV) OL(2+) , where L=2,2'-bipyridine or 1,10-phenanthroline (phen), and of trypsin with V(IV) O(picolinato)2 and V(V) O2 (phen)(+) moieties. Computational studies complete the refinement and shed light on the relevant role of hydrophobic interactions, hydrogen bonds, and microsolvation in stabilizating the structure. Noteworthy is that the trypsin-V(V) O2 (phen) and trypsin-V(IV) O(OH)(phen) adducts correspond to similar energies, thus suggesting a possible interconversion under physiological/biological conditions. The obtained data support the relevance of hydrolysis of V(IV) and V(V) complexes in the several types of binding established with proteins and the formation of different adducts that might contribute to their pharmacological action, and significantly widen our knowledge of vanadium-protein interactions.
