Abstract

Glucose 6 phosphate dehydrogenase has been purified 1000 fold from pig liver. This enzyme exists as an active dimer of molecular weight 133,000 and an inactive monomer of molecular weight 67,500. The pH of maximum activity is 8.5 and the ionic strength maximum is 0.1 to 0.5 M. Glucose 6 phosphate dehydrogenase is highly specific for NADP+ and glucose 6 phosphate. Apparent K(m) values of 3.6 μM and 5.4 μM were obtained for glucose 6 phosphate and NADP+. This enzyme is located almost entirely within the soluble portion of the cellular cytoplasm.
