“…The active site of the TMPRSS2 showed hydrogen bonding with the residues SER460, ASN418, LYN342, THR341, PO4501, GLU299, GLY464, ASP435, ASN343, ASP345, LYS342, TYR337 which played a significant role in binding with the ligands as analyzed from the binding interaction analysis. Similar results with different molecules were shown in different computational and experimental studies [ 36 , 46 , [63] , [64] , [65] , [66] , [67] , [68] , [69] , [70] , [71] ]. In our previous work, GLU299, GLY464, ASP435, PO4501, SER460, SER436, LYS342, ASN418, LYS340, TRP461, PO4 501, THR341 showed H-bond with the ligand [ 46 , 64 ].…”
