Phosphatidylinositol-hydrolyzing activities were found in mitochondrial, lysosomal, microsomal, and cytosol fractions of chicken liver. At least two different activities were detected; cytosolic activiti(es) was maximally exhibited around pH 6.0, activated by Ca2+, and inhibited by EDTA; whereas lysosomal activiti(es) had a optimal pH 5.0, being unaffected by Ca2+ or EDTA.
