2019nCoV (SARS-CoV-2) Mpro (3CLpro, 3C-Like protein, Nsp5)
About Coronavirus Mpro (Coronavirus 3CLpro, 3C-Like protein)
COVID-19 pandemic is caused by 2019nCoV (SARS-CoV-2) infection. 2019nCoV contains 16 Non-structure protein (Nsp1-Nsp16) that may be drugable targets for antiviral compounds discovery against COVID-191.
2019nCoV (SARS-CoV-2) Mpro (Main Protease,Nsp5), also called 3C-Like Protein (3CLpro). The 2019nCoV (SARS-CoV-2) Mpro (3CLpro) mediates processing at 11 distinct cleavage sites, including its own autoproteolysis, and is essential for coronavirus replication. The coronavirus Mpro (3CLpro) exhibits a conserved three-domain structure and catalytic residues1,2.
