An electrospray ionization mass spectrometry study of copper adducts of protonated ubiquitin

A study of the addition of Cu(II) to a ubiquitin electrospray solution shows that the copper ion in the ubiquitin remains doubly charged and displaces two protons on the protonated protein molecule. This observation indicates a chelating bond between the protein and the Cu(II) species. The addition...
