ACE2

ACE2 is a single-pass, transmembrane protease enzyme that has high homology with angiotensin-converting enzyme (ACE). It is the host cell receptor for several coronaviruses but also plays a role in the renin-angiotensin system where it inactivates angiotensin II by converting it to angiotensin 1-7.

ACE2 (E.C. 3.4.17.23), also known as angiotensin-converting enzyme homolog (ACEH) is a single-pass, transmembrane zinc metalloprotease enzyme, found in the lungs, heart, arteries, kidneys, intestines and several brain areas. The protein structure of ACE2 has a single extracellular catalytic domain and a C-terminal transmembrane anchor with a short cytoplasmic tail. ACE2 has a high homology with angiotensin-converting enzyme (ACE) and plays a role in the Renin-Angiotensin System. The primary function of ACE2 is to cleave angiotensin I (Ang I) to give angiotensin 1-9 and angiotensin II (Ang II) to give angiotensin 1-7 (Ang 1-7). Ang 1-7 is a vasodilator peptide that acts at the G-protein coupled receptor, MAS1, counteracting vasoconstriction caused by Ang II. ACE2 can also cleave a number of other peptides including apelin, neurotensin, and ghrelin.

ACE2 is the point of entry for coronaviruses into cells, including SARS-CoV, which causes severe acute respiratory syndrome (SARS) and SARS-CoV-2, which causes COVID-19. The spike S glycoprotein found on the viral cell surface mediates host-cell receptor recognition and membrane fusion by binding to the protease domain of ACE2, enabling viral entry by endocytosis. This entry process is assisted by priming of the S protein by the host cell serine protease, TMPRSS2.
