In this research, by comparing the process of the MD simulation of monomer with dimer, our aim is to (i) find the structural variations and dynamics of the active site residues in SARS M pro monomer in contrast to the dimer, which result in an inactive monomer and provide useful information for receptor based drug design; (ii) investigate the detailed specific interactions involving the two monomers within the dimer and its functional roles in maintaining the activity of the dimer, which provides insights for the design of specific protease inhibitors using the interface of the dimer as a new target. ./cache/cord-279172-d2algx16.txt ./txt/cord-279172-d2algx16.txt
