3.4.21.B60 | in silico binding analysis and molecular docking between TMPRSS2 and SARS-CoV-2 spike protein. TMPRSS2 binds in close proximity to two cleavage sites of the spike glycoprotein. Inhibitor camostat mesylate binds to the central cleft of TMPRSS2 via hydrogen bonding interactions with the residues C281, C297, V280, S436, W461 and G462. Inhibitor nafamostat forms 3 hydrogen bonds |
