MethodsEnzyme Assay. Enzymatic activity was measured by using a spectrophotometric assay with methylglyoxal as the 2-ox-aldehyde substrate (Racker, 1951; Marmstál et al., 1979). Protein concentrations were determined by measuring the absorbance at 280 nm [e= 0.80 (mg/mL)™ 1]. The specific activity of the pure enzyme was 1300 units/mg.
