The lysosomal fraction of rat liver has been investigated with the view to determining the possible multiplicity of enzymes exhibiting phosphatase activity. After ammonium sulfate purification, diethylaminoethyl cellulose chromatography resolved the enzyme mixture into a nucleotidase with maximum activity at pH 5.0, and a fraction possessing sugar phosphate phosphohydrolase activity with a pH optimum at 4.0.
