about.
1.Researchers have used cryogenic elecron microscOpy fo show that corona vruses
enter human cels through an interccfion with angiolersin converting eneyme 2 (ACE2).
Scienfsts explaring how corona viruses lke COVID-19 infect human cels have shown that
the SARS-CoV-2 spke (3) ghycoprotein binds to the cel membrane protein angiotensin
convering enzyme 2 [ACE2 fo enfer human ces. COvID-19 has been shown fo bind to
ACE2 via the S protein on its surface. Duing infection, the S protein is cleaved into
sLbunits.$l and 2.s1 contains the receptor binding domain (RBD) which alaws corona
vruses to drecthy bind to the peptidase doman (PD) of ACE2. S2 then ikely playsa rale in
membrane fusion.
