10 - 10.5
maximal activities of the three allelic forms are obtained within a pH range of 10.0-10.5 for glycerol 3-phosphate oxidation
5 - 7.5
5 - 8.1
about half-maximal activity at pH 5.0 and 8.1, reduction of dihydroxyacetone phosphate
5.2 - 7.8
about half-maximal activity between pH 5.2 and 7.8, reduction of dihydroxyacetone phosphate
5.8 - 7.2
reduction of dihydroxyacetone phosphate occurs over a broad range between 5.8 to 7.2
6 - 6.5
maximal activities of the three allelic forms are obtained within a pH range of 6.0-6.5 for dihydroxyacetone phosphate reduction
6.5 - 8.2
about half-maximal activity at pH 6.5 and 8.2, reduction of dihydroxyacetone phosphate
6.7 - 8.7
about 80% of maximal activity at pH 6.7 and 8.7, reduction of dihydroxyacetone phosphate, decrease of activity below and above these pH values
6.8 - 7.2
activity falls off rapidly as pH is increased
7 - 8
dihydroxyacetone reduction, activity decreases rapidly below pH 7.0 and above pH 8.0, more rapidly at acidic values
7.5 - 8
pH-rate profile for the reduction of dihydroxyacetone phosphate shows rather sharp optimum between pH 7.5 and 8.0
7.9 - 8.2
maximum activity in pH interval 7.9-8.2
8 - 10
about half-maximal activity at pH 8.0 and 10.0, oxidation of glycerol 3-phosphate, isozymes P-III, liver
8 - 11
about half-maximal activity at pH 8.0 and 11.0, oxidation of L-glycerol-3-phosphate
8.1 - 9.4
about 80% of maximal activity at pH 8.1 and 9.4, oxidation of glycerol-3-phosphate, decrease of activity below and rapidly above these pH values
8.6 - 10
about half-maximal activity at pH 8.6 and 10.0, oxidation of glycerol 3-phosphate
additional information
A change in pH from pH 8.0 to pH 7.5 leads to increased G3PDH affinity for NAD+. With a change in pH from pH 8.0 to pH 7.5 at 22C in the euthermic and hibernator conditions, the Km for NAD+ decreases by 62% and 53%, respectively
