Abstract

A novel coronavirus has been identified as the causative agent of severe acute respiratory syndrome (SARS). The viral main proteinase (M^pro, also called 3CL^pro), which controls the activities of the coronavirus replication complex, is an attractive target for therapy. We determined crystal structures for human coronavirus (strain 229E) M^pro and for an inhibitor complex of porcine coronavirus [transmissible gastroenteritis virus (TGEV)] M^pro and we constructed a homology model for SARS coronavirus (SARS-CoV) M^pro. The structures reveal a remarkable degree of conservation of the substrate-binding sites, which is further supported by recombinant SARS-CoV M^pro-mediated cleavage of a TGEV M^pro substrate. Molecular modeling suggests that available rhinovirus 3C^pro inhibitors may be modified to make them useful for treating SARS.
