1) Renin-like enzyme of rat aorta was purified by chromatography with DEAE-cellulose and Sephadex G-200. 2) The molecular weight of renin-like enzyme was 124,000 and 72,000 on Sephadex G-200 gel filtration. The isozymes, however, migrated as a single band with molecular weight of 71,000 on SDS/polyacrylamide gel electrophoresis. These isozymes showed the same optimal pH (6.5) and temperature (37℃). 3) Renin-like enzyme showed high activity in the microsomal fraction of the aorta. 4) In one-clip, two-kidney Goldblatt hypertensive rats, the aortic renin concentration increased significantly, but not parallel with the activity in plasma. 5) Renin, widely distributed in subcellular fractions of the aorta, may play a possible role in the local control of vascular tone. It is likely that renin in vascular wall is of local origin.
