IUBMB Comments

The enzyme, present in mammalia, cleaves and inactivates EC 3.4.17.23, angiotensin-converting enzyme 2 (ACE2), at arginine residues in the region R697 to R716, which enhances influenza and coronavirus uptake . The enzyme also cleaves and activates influenza and coronavirus spike glycoproteins and thus facilitates virus-cell membrane fusions. The cleavage of SARS-COV2 spike glycoprotein occurs between the S2 and S2′ site at SKPSKR/SFIEDL, while the cleavage of MERS-COV glycoprotein occurs at GSRSAR/SAIEDL.
