Abstract
Vitamin A alcohol activates arylsulfatase (aryl-sulfatesulfohydrolase, EC 3-1.6.1) and inhibits β-glucuronidase (β-d-glucuronide glucuronohydrolase, EC 3.2.1.31) of rat colon. These effects were less pronounced with vitamin A acetate and they were negligible with vitamin A acid and other chemically related compounds. Action of vitamin A alcohol was not dependent upon the integrity of a particulate membrane and was unaffected by removal of lipid from the enzyme suspension, suggesting a direct effect on the enzyme proteins. Kinetics of arylsulfatase and β-glucuronidase were altered in the presence of vitamin A alcohol. Solubilized arylsulfatase and β-glucuronidase of particulate fractions from rat small intestine, kidney and liver showed the same response to vitamin A as the colon enzymes.
