a, The chemical structure of N1 inhibitor. b, The binding mode of COVID-19 virus Mpro (blue sticks) with N3 (green sticks). c, The binding mode of SARS-CoV Mpro (grey sticks) with N1 (pink sticks). The hydrogen bonds formed by water (W1) are indicated by the dashed lines.

a, Comparison of inhibitor binding mode between the structures of COVID-19 virus Mpro-N3 and SARS-CoV Mpro-N1. COVID-19 virus Mpro is shown in marine cartoon; SARS-CoV Mpro in grey; N3 in green sticks; N1 in hot pink. b, Superposition of crystal structures of Mpros (Cα 1-300) from 12 CoVs, including COVID-19 virus, SARS-CoV, MERS-CoV, HCoV-HKU1, BtCoV-HKU4, MHV-A59, PEDV, FIPV, TGEV, HCoV-NL63, HCoV-229E and IBV The color spectrum represents the root-mean-square deviation (RMSD) of the aligned Cα atoms. c, Surface presentation of conserved substrate-binding pockets of 12 CoV Mpros. Red: residues are entirely identical among all 12 Mpros; violet: conserved substitution in one CoV Mpro; orange: conserved substitution in more than one CoV Mpros. S1, S2, S4, and S1’ subsites are indicated.
