Abstract
Summary
Evidence is presented indicating that lysosomal release sites for acid phosphatase and β-glucuronidase differ. ATP stabilized the release of both acid hydrolases. However, ATP in the presence of cysteine stabilized the release of acid phosphatase but not β-glucuronidase. Some of the data obtained suggest the possible involvement of a lysosomal membrane bound ATPase in controlling acid hydrolase release.
