Two associated enzymes, 3-dehydroquinate hydro-lyase (EC 4.2.1.10) and shikimate:NADP+ oxidoreductase (EC 1.1.1.25), have been purified from Phaseolus mungo seedlings. These enzymes were purified 6900- and 9700-fold, respectively, but they were not separable. Moreover, two activity bands of the shikimate:NADP+ oxidoreductase were detected after polyacrylamide gel electrophoresis and the two peaks also have 3-dehydroquinate hydro-lyase activity. The two forms of the associated enzymes showed only small differences in molecular weight, Km value, pH optimum and the responses to some inhibitors.
