1.2.1.90 additional information - D-glyceraldehyde 3-phosphate the saturation with D-glyceraldehyde 3-phosphate follows classical Michaelis-Menten kinetics, showing half-maximal saturation at 50 mM. A definite Km for the free aldehyde, the presumed substrate of the enzyme, cannot be given because the portion of the free aldehyde in aqueous solution could not be determined at 70 °C 727825 1.2.1.90 0.02 - D-glyceraldehyde 3-phosphate pH 7.0, 45°C 727454 1.2.1.90 0.02 - D-glyceraldehyde 3-phosphate pH 7.0, 70°C 727454 1.2.1.90 0.23 - NADP+ pH 8.5, 30°C, recombinant enzyme, with succinate semialdehyde 762770 1.2.1.90 0.4 - NAD+ pH 8.5, 30°C, recombinant enzyme, with succinate semialdehyde 762770 1.2.1.90 1 - NAD+ pH 7.0, 45°C 727454 1.2.1.90 1.9 - D-glyceraldehyde 3-phosphate pH 8.5, 30°C, recombinant enzyme, with NADP+ 762770 1.2.1.90 2.2 - D-glyceraldehyde 3-phosphate pH 8.5, 30°C, recombinant enzyme, with NAD+ 762770 1.2.1.90 3 - L-Glyceraldehyde 3-phosphate about, pH 8.5, 30°C, recombinant enzyme, with NADP+ 762770 1.2.1.90 3.1 - NAD+ pH 7.0, 70°C 727454
