WebJan 7, 2024 · Here we confirm the 3’-5’ exoribonuclease and MTase activities of nsp14 in this new Coronavirus, and the critical role of nsp10 in upregulating the nsp14 ExoN activity in vitro. Furthermore, we demonstrate that SARS-CoV-2 nsp14 N7-MTase activity is functionally independent of the ExoN activity. WebOct 26, 2024 · This includes nsp12, an RNA-dependent RNA polymerase (RdRp), RNA helicase (Hel/nsp13), and a proofreading exoribonuclease, among others.

WebMay 6, 2024 · Within the SARS-CoV-2 replicase machinery, nsp14 is a bifunctional protein with a putative N-terminal exoribonuclease (ExoN) domain playing a proofreading role in RNA replication and an assumed C-terminal guanine-N7-methyltransferase (N7-MTase) domain responsible for mRNA capping ( 12–14 ). WebThe 5´ → 3´ exoribonuclease XRN2/RAT1 is involved in 5´ → 3´ RNA decay. Fungal studies with XRN2 and conditional mutants have illustrated the crucial role of this enzyme, suggesting XRN2 should be considered as target to searching for novel inhibitors that might be used as fungicides to control Panama disease. Webfeasible; therefore, alternative approaches to crop protection must be developed. The 5´ → 3´ exoribonuclease XRN2/RAT1 is involved in 5´ → 3´ RNA decay.
