Figure 3

Electrospray ionization mass spectra of reaction mixtures containing 1 to 1 ratio of Hg(II):tetrapeptides. (a) GCGC + Hg2+, (b) ECGC + Hg2+, (c) HCGC + Hg2+, (d) WCGC + Hg2+, and the m/z value of the most intense peak in each isotopic cluster. Insets show the experimental and calculated mercury isotopic patterns for the 1 : 1 mercuriated peptide adducts.
