摘要: 1. Kidney angiotensinases are located in two kinds of subcellular fraction-lysosomal and microsomal. Lysosomal angiotensinase is active at an acid pH inhibited by DFP, suggesting a relationship to plasma angiotensinase. Most the activity was released from particles freezing thawing. The microsomal enzyme near neutral pH, activated calcium ion EDTA . 2. About 70 per cent renin lysosomal fraction rat kidney freeze-thaw method. It revealed only one peak on either Sephadex G-100 gel filtration or DEAE-cellulose column chromatography. molecular weight calculated as 40, 000-50, 000. 3. At least three components ATPase were found
