The renin–angiotensin system (RAS) is a central regulator of cardiovascular and renal functions and plays a key role in the pathophysiology of various cardiovascular and renal diseases. The RAS consists of a series of enzymatic reactions culminating in the generation of angiotensin II (Ang II) in plasma as well as in various tissues including the heart and kidneys. The discovery of angiotensin-converting enzyme 2 (ACE2) had added a new dimension to the RAS [1–5]. Human and rodent ACE2 are similar proteins containing 805 amino acids that include an N-terminal signal sequence, a single active-site catalytic region and a C-terminal hydrophobic membrane-anchor region [2,3,5]. ACE2 functions predominantly as a carboxymonopeptidase with a substrate preference for hydrolysis between proline and a hydrophobic or basic C-terminal residue [6]. Both ACE and ACE2 are endothelium-bound carboxypeptidases with ACE2 protein being highly expressed in the heart and
