  • Biochemical and structural insights into SARS-CoV-2 polyprotein processing by Mpro

    • Authors : Yadav, Ruchi (2023)

  • SARS-CoV-2, a human coronavirus, is the causative agent of the COVID-19 34 pandemic. Its ~30 kb RNA genome is translated into two large polyproteins subsequently cleaved 35 by viral papain-like protease and main protease (Mpro/nsp5). Polyprotein processing is essential 36 yet incompletely understood. We studied Mpro-mediated processing of the nsp7-10/11 37 polyprotein, whose mature products are cofactors of the viral replicase, identifying the&#...

  • More than just a ticket canceller: The mitochondrial processing peptidase matures complex precursor proteins at internal cleavage sites

    • Authors : Jana, Friedl; Knopp, Michael R (2020)

  • Most mitochondrial proteins are synthesized in the cytosol as precursors that carry N-terminal presequences. After import into mitochondria, these targeting signals are cleaved off by the mitochondrial processing peptidase MPP, giving rise to shorter mature proteins. Using the mitochondrial tandem protein Arg5,6 as a model substrate, we demonstrate that MPP has an additional role in preprotein maturation, beyond the removal of presequences. Arg5,6 is synthesized a...
