In this recent publication, metalation of hen egg white lysozyme (HEWL) with organometallics was studied with physicochemical methods in solid state, solution and the gas phase. While metalation did not affect the crystal structure of HEWL significantly, protein destabilisation was detected in gas phase and solution.
