Erythrocyte and liver tissue delta-aminolevulinate dehydratase activity is determined in rats fed a semipurified diet under controlled nutritional intake of zinc (7440666) and copper (7440508). A significant decrease in enzymatic activity is observed in animals fed a low zinc diet, while dietary copper has no effect. In vitro addition of zinc to the erythrocyte preparations obtained from rats on low zinc diet produces a slight increase in enzymatic activity. Though zinc is the metal ion activator of the enzyme, the requirement of zinc is at the site of enzyme synthesis.
