Angiotensin I-converting enzyme (ACE, EC 3.4.15.1), an exopeptidase, is a circulating enzyme that participates in the body's renin-angiotensin system (RAS), which mediates extracellular volume (i.e. that of the blood plasma, lymph and interstitial fluid), and arterial vasoconstriction. It is secreted by pulmonary and renal endothelial cells and catalyzes the conversion of decapeptide angiotensin I to octapeptide angiotensin II.[1]

[edit] Functions

It has two primary functions:

These two actions make ACE inhibition a goal in the treatment of conditions such as high blood pressure, heart failure, diabetic nephropathy, and type 2 diabetes mellitus. Inhibition of ACE (by ACE inhibitors) results in the decreased formation of angiotensin II and decreased metabolism of bradykinin, leading to systematic dilation of the arteries and veins and a decrease in arterial blood pressure. In addition, inhibiting angiotension II formation diminishes angiotensin II-mediated aldosterone secretion from the adrenal cortex, leading to a decrease in water and sodium reabsorption and a reduction in extracellular volume.[5]

[edit] Genetics & C and N Domains With Important Functional Difference

The ACE gene, ACE, encodes 2 isozymes. The somatic isozyme is expressed in many tissues, mainly in the lung, including vascular endothelial cells, epithelial kidney cells, and testicular Leydig cells, whereas the germinal is expressed only in sperm. Brain has ACE enzyme which takes part in local RAAS and converts Aß42 ( plaquogenic ) to Aß40( more soluble and removal ) forms of Beta amyloid ; latter is predominantly a function of N domain portion on the ACE enzyme; Inhibition of ACE with ACE Inhibitors, especially Blood Brain Barrier crossing and with preferentially select N terminal activity would cause accumulation of Aß42 which is plaquogenic causing progression of dementia; preferential C domain active BBB crossing ACE would likely have less of this latter effect.
