Mouse spermatozoal glucose-6-phosphate dehydrogenase is the X-linked form

Mouse spermatozoal “glucose-6-phosphate dehydrogenase” was characterized for substrate utilization, electrophoretic mobility, and by immunoinactivation with an antibody to human, erythrocytic glucose-6-phosphate dehydrogenase. The enzymatic activity was found to have the properties of the X-linked form ($\text{Gpd-2}$).
