Summary:The effects of various compounds on ascorbate-2-sulfate sulfohydrolase and arylsulfatase [EC 3.1. 6.1] activities in the copurified preparation from the liver of Charonia lampas were investigated.. The former activity was competitively inhibited by inorganic phosphate and sulfate. The latter was not affected by sulfate. Higher concentrations of sodium chloride inhibited the former and activated the latter. Neither of the activities was inhibited by sulfhydryl reagents. Both activities were competitively inhibited by the other substrate.
