Abstract: Angiotensin - converting enzyme was extracted by differential centrifugation, the solubilization of sodium deoxycholate, DEAE - cellulose column chromatography and Sephadex G - 200 column gel filtration. A series of studies on angiotensin - converting enzyme indicated that it had molecular weight of 302KD, the sugar content was 19. 3% and the optimum temperature and pH were 37℃ and 8. 3 respectively.
