Figure 5.
Detection of SAH indicates formation of Diso in CPDisoGRC. The chromatograms of assay solutions of CPNGRC peptide that were kept at pH 7.5 on ice (bottom) or pH 8.5 at 37°C overnight (top). In the top panel, an arrow indicates the elution of SAH, which is a product of the methyltransferase reaction with Diso.
