Angew.Chem.Int.Ed.Engl., 63:e202406669-e202406669, 2024 Cited by PubMed Abstract: The high-resolution X-ray structures of the model protein lysozyme in the presence of the potential drug [VO(acetylacetonato)] from crystals grown in 1.1 M NaCl, 0.1 M sodium acetate at pH 4.0 reveal the binding to the protein of different and unexpected mixed-valence cage-like polyoxidovanadates (POVs): [VO(OH)], which non-covalently interacts with the lysozyme surface, [VO(OH)] and [VO(OH)] (this latter based on an unusual {VO} cage) which covalently bind the protein. EPR spectroscopy confirms the partial oxidation of V to V and the formation of mixed-valence species. The results indicate that the interaction with proteins can stabilize the structure of unexpected - both for dimension and architecture - POVs, not observed in aqueous solution.
