Abstract

Two forms of glucose-6-phosphate dehydrogenase, A and B, have been reported in deer mouse tis sues. The B enzyme, which showed autosomally controlled polymorphism, is now found to be equally active to ward glucose-6-phosphate and galac tQse-6- phosphate; the A enzyme is specific for the former. Human and horse livers also have two forms of glucose-6-phosphate dehydrogenase which exhibit the same substrate spe cifities as those in the deer mouse. A wide variety of electrophoretic patterns was seen in the human galactose-active enzyme.
