The SARS-CoV-2 Spike Glycoprotein Directly Binds Exogeneous Sialic Acids: A NMR View
The interaction of the SARS CoV2 spike glycoprotein with two sialic acid-containing trisaccharides (a2,3 and a2,6 sialyl N-Acetyllactosamine) has been demonstrated by NMR. The NMR-based distinction between the signals of those sialic acids in the glycans covalently attached to the spike protein and those belonging to the exogenous a2,3 and a2,6 sialyl N-Acetyllactosamine ligands has been achieved by synthesizing uniformly 13C-labelled trisaccharides at the sialic acid and galactose moieties....
