A New Fragment-Based Pharmacophore Virtual Screening Workflow Identifies Potent Inhibitors of SARS-CoV-2 NSP13 Helicase. [PDF]
The new fragment‐based pharmacophore virtual screening workflow FragmentScout is introduced, which aggregates feature information present in each experimental fragment pose from XChem high‐throughput crystallographic screening. The method is applied to the SARS‐CoV‐2 NSP13 helicase, and we report the in silico discovery of 13 novel micromolar potent ...

Mechanism of duplex unwinding by coronavirus nsp13 helicases [PDF]
Abstract The current COVID-19 pandemic urges in-depth investigation into proteins encoded with coronavirus (CoV), especially conserved CoV replicases. The nsp13 of highly pathogenic MERS-CoV, SARS-CoV-2, and SARS-CoV exhibit the most conserved CoV replicases.

Nucleotide-bound crystal structures of the SARS-CoV-2 helicase NSP13. [PDF]
Nucleotide-bound crystal structures of SARS-CoV-2 NSP13 in ADP- and ATP-bound states were resolved to 1.8 and 1.9 Å, respectively. The ADP-bound model captures a state immediately following ATP hydrolysis, with both ADP and orthophosphate still present in the active site.

The NSP5, ORF6 and NSP13 of SARS-CoV-2 Cooperate to Modulate Inflammatory Cell Death Activation. [PDF]
ZBP1 is capable of initiating a large cell death complex to induce programmed cell death during SARS‐CoV‐2 infection. However, SARS‐CoV‐2 can inhibit the activation of ZBP1‐mediated cell death by targeting key components of this complex. This suppression of ZBP1‐mediated cell death may account for the increased mortality observed in patients co ...

The nsp1, nsp13, and M Proteins Contribute to the Hepatotropism of Murine Coronavirus JHM.WU [PDF]
ABSTRACT Mouse hepatitis virus (MHV) isolates JHM.WU and JHM.SD promote severe central nervous system disease. However, while JHM.WU replicates robustly and induces hepatitis, JHM.SD fails to replicate or induce pathology in the liver.

Five-Year (2017-2022) Evolutionary Dynamics of Human Coronavirus OC43 in Southern France Based on Whole Genome Next-Generation Sequencing. [PDF]
ABSTRACT HCoV‐OC43 genomes and their evolution are scarcely studied worldwide and in France, with only 361 genomes available as of October 2023. Here, an in‐house PCR amplification system was implemented to obtain retrospectively by next‐generation sequencing, then analyze HCoV‐OC43 genomes for infections diagnosed with this virus in southern France ...

SARS-CoV-2 Nonstructural Proteins 1 and 13 Suppress Caspase-1 and the NLRP3 Inflammasome Activation
Viral infection-induced activation of inflammasome complexes has both positive and negative effects on the host. Proper activation of inflammasome complexes induces down-stream effector mechanisms that inhibit viral replication and promote viral ...
