T16 0-179 Sentence denotes These trimeric S proteins mediate host-cell entry with the S1 and S2 subunits responsible for binding to the host-cell receptor and facilitating membrane fusion, respectively9–11.
T17 180-341 Sentence denotes MERS S binds to dipeptidyl-peptidase 4 (DPP4)12, whereas SARS S13 and SARS-CoV-214,15 utilize angiotensin-converting enzyme 2 (ACE2) as a host cellular receptor.
T18 342-576 Sentence denotes CoV S proteins are the largest class I viral fusion proteins known9, and are extensively glycosylated, with SARS and MERS S glycoproteins both encoding 69 N-linked glycan sequons per trimeric spike with SARS-CoV-2 containing 66 sites.
T19 577-722 Sentence denotes These modifications often mask immunogenic protein epitopes from the host humoral immune system by occluding them with host-derived glycans16–18.
T20 723-991 Sentence denotes This phenomenon of immune evasion by molecular mimicry and glycan shielding has been well characterised across other viral glycoproteins, such as HIV-1 envelope protein (Env)19–21, influenza hemagglutinin (HA)22,23 and Lassa virus glycoprotein complex (LASV GPC)24–26.
