Angiotensin-converting enzyme (EC 3.4.15.1), or ACE, is a central component of the renin–angiotensin system (RAS), which controls blood pressure by regulating the volume of fluids in the body. It converts the hormone angiotensin I to the active vasoconstrictor angiotensin II .

Outside the liver, angiotensinogen is picked up from the circulation or expressed locally in some tissues; with renin they form angiotensin I, and locally expressed angiotensin-converting enzyme, chymase or other enzymes can transform it into angiotensin II. [13] [14] [15] This process can be intracellular or interstitial. [9]
Angiotensin is a peptide hormone that causes vasoconstriction and an increase in blood pressure. It is part of the renin–angiotensin system, which regulates blood pressure. Angiotensin also stimulates the release of aldosterone from the adrenal cortex to promote sodium retention by the kidneys. An oligopeptide, angiotensin is a hormone and a ...
Aldosterone synthase is a protein which is only expressed in the zona glomerulosa [5] of the adrenal cortex and is primarily regulated by the renin–angiotensin system. [6] It is the sole enzyme capable of synthesizing aldosterone in humans and plays an important role in electrolyte balance and blood pressure. [7]
Blood pressure and fluid and electrolyte homeostasis is regulated by the renin–angiotensin–aldosterone system. [1] Renin, an enzyme released from the kidneys, converts the inactive plasma protein angiotensinogen into angiotensin I (Ang I). Then Ang I is converted to Ang II with angiotensin converting enzyme (ACE), see figure 2. Ang II in ...
Carboxypeptidase A and the target enzyme of Captopril, angiotensin-converting enzyme, have very similar structures, as they both contain a zinc ion within the active site. This allowed for a potent carboxypeptidase A inhibitor to be used to inhibit the enzyme and, thus, lower blood pressure through the renin-angiotensin-aldosterone system. [1]
Benter et al were the first to report that Ang-(1-7) behaves in a way opposite to that of Ang II and that intavenous administration of Ang-(1-7) produces blood pressure lowering effects by activating its own receptor [5] Angiotensin (1-7) is a vasodilator agent affecting cardiovascular organs, such as heart, blood vessels and kidneys, with ...
