The papain-like protease from the severe acute respiratory syndrome coronavirus is a deubiquitinating enzyme.
The severe acute respiratory syndrome coronavirus papain-like protease (SARS-CoV PLpro) is involved in the processing of the viral polyprotein and, thereby, contributes to the biogenesis of the virus replication complex. Structural bioinformatics has revealed a relationship for the SARS-CoV PLpro to herpesvirus-associated ubiquitin-specific protease (HAUSP), a ubiquitin-specific protease, indic...
متن کاملThe papain-like protease of severe acute respiratory syndrome coronavirus has deubiquitinating activity.
Replication of the genomic RNA of severe acute respiratory syndrome coronavirus (SARS-CoV) is mediated by replicase polyproteins that are processed by two viral proteases, papain-like protease (PLpro) and 3C-like protease (3CLpro). Previously, we showed that SARS-CoV PLpro processes the replicase polyprotein at three conserved cleavage sites. Here, we report the identification and characterizat...
متن کاملSevere acute respiratory syndrome coronavirus papain-like protease: structure of a viral deubiquitinating enzyme.
Replication of severe acute respiratory syndrome (SARS) coronavirus (SARS-CoV) requires proteolytic processing of the replicase polyprotein by two viral cysteine proteases, a chymotrypsin-like protease (3CLpro) and a papain-like protease (PLpro). These proteases are important targets for development of antiviral drugs that would inhibit viral replication and reduce mortality associated with out...
متن کاملDeubiquitination, a new function of the severe acute respiratory syndrome coronavirus papain-like protease?
A new coronavirus has been identified as the infectious agent of severe acute respiratory syndrome (SARS). Although SARS was successfully contained by quarantine measures, the reconstructed itinerary of the virus through 30 countries and its high mortality rate illustrate the global threat that this newly emerging disease represents (17). During the expression of the SARS coronavirus (SCoV) gen...
متن کاملIdentification of severe acute respiratory syndrome coronavirus replicase products and characterization of papain-like protease activity.
Gene 1 of the coronavirus associated with severe acute respiratory syndrome (SARS) encodes replicase polyproteins that are predicted to be processed into 16 nonstructural proteins (nsps 1 to 16) by two viral proteases, a papain-like protease (PLpro) and a 3C-like protease (3CLpro). Here, we identify SARS coronavirus amino-terminal replicase products nsp1, nsp2, and nsp3 and describe trans-cleav...
