Structural Basis for the Ubiquitin-Linkage Specificity and deISGylating Activity of SARS-CoV Papain-Like Protease
Severe acute respiratory syndrome coronavirus (SARS-CoV) encodes a papain-like protease (PLpro) with both deubiquitinating (DUB) and deISGylating activities that are proposed to counteract the post-translational modification of signaling molecules that activate the innate immune response. Here we examine the structural basis for PLpro's ubiquitin chain and interferon stimulated gene 15 (ISG15) ...
متن کاملMERS‐CoV papain-like protease (PLpro): expression, purification, and spectroscopic/thermodynamic characterization
Within a decade, MERS-CoV emerged with nearly four times higher case fatality rate than an earlier outbreak of SARS-CoV and spread out in 27 countries in short span of time. As an emerging virus, combating it requires an in-depth understanding of its molecular machinery. Therefore, conformational characterization studies of coronavirus proteins are necessary to advance our knowledge of the matt...
متن کاملDeubiquitinating and interferon antagonism activities of coronavirus papain-like proteases.
Coronaviruses encode multifunctional proteins that are critical for viral replication and for blocking the innate immune response to viral infection. One such multifunctional domain is the coronavirus papain-like protease (PLP), which processes the viral replicase polyprotein, has deubiquitinating (DUB) activity, and antagonizes the induction of type I interferon (IFN). Here we characterized th...
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 کاملMERS-CoV
In 2002/03, a novel coronavirus (CoV) termed severe acute respiratory syndrome (SARS)-CoV emerged in China and caused an epidemic in which approximately 800 of 8000 cases died. Ten years later, a newly emerged Middle East respiratory syndrome (MERS)-CoV has been confirmed in 189 patients of which 82 had a fatal outcome. All MERS cases were linked to the Arabian Peninsula and to date thirteen ca...
