34518836-6	2021	Molecular dynamics simulations were performed using NAMD to investigate the hydrogen bonds between S proteins and hACE2.	Hydrogen	76-84	surface glycoprotein	Severe acute respiratory syndrome coronavirus 2	99-100	
34518836-7	2021	From the MD simulations it was found that SARS-CoV-2 has four pairsof essential hydrogenbonds (high occupancy, >80%), while SARS-CoV has three pairs, which indicates the SARS-CoV-2 S protein has relatively more robust binding strategy than SARS-CoVS protein.Four key residues forming essential hydrogen bonds from SARS-CoV-2 are identified, which are potential drug targets for COVID-19 treatments.
