MALDI-TOF analysis of YpdE activity. The substrate used was the peptide Gln-Ala-Thr-Val-Gly-Asp-Val-Asn-Thr-Asp-Arg-Pro-Gly-Leu-Leu-Asp-Leu-Lys. The spectrum on the top is the reaction mixture of the substrate with enzyme supplemented with Co2+. The spectrum on the bottom is the control with just the substrate.
