Acid D-ephedrine-O-phosphatase activity in rate ventral prostate lysosomes.

Hydrolysis of D-ephedrine-O-phosphate (DEP) by rat ventral prostrate was investigated by electron microscopic hystochemistry. In contrast to previous reports that DEP is exclusitely hydrolyzed by a secreted nonlysosomal acid phosphatase, enzyme reaction product was present in supranuclear and basal lysosomes.
