Evidence for the existence of a novel enzyme system. myo-Inositol-1-phosphate dehydrogenase in Phaseolus aureus.

Year: 1979

Type: article

Abstract: A novel enzyme system, myo-inositol-1-phosphate dehydrogenase, has been isolated from germinating mung bean seeds. The dehydrogenation and cleavage of myo-inositol 1-phosphate by this enzyme leads to the synthesis of a pentose phosphate which appears to be ribulose 5-phosphate. The pH optimum of the enzyme is 8.6; NAD+ is required as coenzyme and no other nucleotides can replace NAD+. Mono- or divalent cations are not essential for the enzyme activity. Stoichiometry of the reaction suggests that 2 mol of NAD+ are reduced per mol of ribulose-5-P generated.
