Redefining NSP12 activity in SARS-CoV-2 and its regulation by NSP8 and NSP7 [PDF]
RdRp is a critical component of an RNA virus life cycle. Among coronaviruses, NSP12, along with one copy of NSP7 and two copies of NSP8, forms the RdRp holoenzyme and exhibits polymerase activity.

Cellular eEF1G Inhibits Porcine Deltacoronavirus Replication by Binding Nsp12 and Disrupting Its Interaction with Viral Genomic RNA [PDF]
Porcine deltacoronavirus (PDCoV) is an emerging pathogen that causes severe, often fatal, diarrhea in suckling piglets and has zoonotic potential. Its nonstructural protein 12 (Nsp12), functioning as the RNA-dependent RNA polymerase (RdRp), is a central ...

Development of novel monoclonal antibodies against nsp12 of SARS-CoV-2
A novel coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has caused a global pandemic of coronavirus disease 19. Coronaviruses, including SARS-CoV-2, use RNA-dependent RNA polymerase (RdRP) for viral replication and ...

Structural Homology-Based Drug Repurposing Approach for Targeting NSP12 SARS-CoV-2
The severe acute respiratory syndrome coronavirus 2, also known as SARS-CoV-2, is the causative agent of the COVID-19 global pandemic. SARS-CoV-2 has a highly conserved non-structural protein 12 (NSP-12) involved in RNA-dependent RNA polymerase (RdRp ...

The P323L substitution in the SARS-CoV-2 polymerase (NSP12) confers a selective advantage during infection [PDF]
Background The mutational landscape of SARS-CoV-2 varies at the dominant viral genome sequence and minor genomic variant population. During the COVID-19 pandemic, an early substitution in the genome was the D614G change in the spike protein, associated ...

Fisetin as an Antiviral Agent Targeting the RNA-Dependent RNA Polymerase of SARS-CoV-2: Computational Prediction and In Vitro Experimental Validation [PDF]
SARS-CoV-2 continues to evolve into immune-evasive variants, and although vaccination remains the cornerstone of prevention, the search for antiviral molecules targeting conserved viral enzymes remains essential.

Structure of the SARS-CoV nsp12 polymerase bound to nsp7 and nsp8 co-factors [PDF]
The pathogenic human coronaviruses SARS- and MERS-CoV can cause severe respiratory disease. Here the authors present the 3.1Å cryo-EM structure of the SARS-CoV RNA polymerase nsp12 bound to its essential co-factors nsp7 and nsp8, which is of interest for
