generate an imine product. ProtonNMRspectra of ASA done at different pH values shows new NMR peaks at high pH, but not at low pH, confirming the presence of reaction products for ASA at high pH. The enzymatic product of the DHDPS reaction was examined at low pH by protonNMR starting with either 3 h-pyruvate or 3 d-pyruvate and identical NMRspectra were obtained with four new NMR peaks observed at 1.5
