renin

A proteinase of high specificity that is released by the kidney and acts to raise blood pressure by activating angiotensin.

An circulating enzyme released by mammalian kidneys that converts angiotensinogen to angiotensin-I. Because its activity ultimately leads to formation of angiotensin-II and aldosterone, this hormone plays a role in maintaining blood pressure.

a proteolytic enzyme secreted by the kidneys; catalyzes the formation of angiotensin and thus affects blood pressure
