The pandemics have always been a destructive carrier to living organisms. Humans are the ultimate victims, as now we are facing the SARS CoV-2 virus caused COVID-19 since its emergence in Dec 2019, at Wuhan (China). Due to the new coronavirus' unexplored nature, we shed light on curcumin for its potential role against the disease. The Nsp9 replicase protein, which plays an essential role in virus replication, was extracted online, followed by 3D PDB model prediction with its validation. The in silico molecular docking of curcumin with the replicase enzyme gave insights into the preventive measures against the virus as curcumin showed multiple interactions with Nsp9 replicase. The current study showed the use of curcumin against the coronavirus and its possible role in developing medicine against it.

Article Synopsis
  • SARS-CoV-2 is the virus behind the COVID-19 pandemic, and this study aimed to understand how its replication works by analyzing 11 nonstructural replicase proteins.
  • Researchers used antibodies to track the location and expression of these proteins in infected cells, finding that certain proteins like nsp3, nsp5, and nsp8 appeared in specific areas (perinuclear foci) and showed changes over time.
  • The study also discovered that viral dsRNA, a replication intermediate, formed in these foci shortly after infection, suggesting a timeline for viral replication and providing tools for future research in diagnostics and antiviral development.

A natural product compound inhibits coronaviral replication in vitro by binding to the conserved Nsp9 SARS-CoV-2 protein.

The Nsp9 replicase is a conserved coronaviral protein that acts as an essential accessory component of the multi-subunit viral replication/transcription complex. Nsp9 is the predominant substrate for the essential nucleotidylation activity of Nsp12. Compounds specifically interfering with this viral activity would facilitate its study.

Binding of a pyrimidine RNA base-mimic to SARS-CoV-2 nonstructural protein 9.

Infection and Immunity Program, Department of Biochemistry and Molecular Biology, Biomedicine Discovery Institute, Monash University, Clayton, Victoria, Australia; Institute of Infection and Immunity, Cardiff University School of Medicine, Cardiff, United Kingdom. Electronic address:

The coronaviral nonstructural protein 9 (Nsp9) is essential for viral replication; it is the primary substrate of Nsp12's pseudokinase domain within the viral replication transcription complex, an association that also recruits other components during different stages of RNA reproduction. In the unmodified state, Nsp9 forms an obligate homodimer via an essential GxxxG protein-interaction motif, but its ssRNA-binding mechanism remains unknown. Using structural biological techniques, here we show that a base-mimicking compound identified from a small molecule fragment screen engages Nsp9 via a tetrameric Pi-Pi stacking interaction that induces the formation of a parallel trimer-of-dimers.

The current crisis of the COVID-19 pandemic around the world has been devastating as many lives have been lost to the novel SARS CoV-2 virus. Thus, there is an urgent need for the right therapeutic drug to curb the disease. However, there is time constraint in drug development, hence the need for drug repurposing approach, a relatively fast and less expensive alternative.

Identification of an Intramolecular Switch That Controls the Interaction of Helicase nsp10 with Membrane-Associated nsp12 of Porcine Reproductive and Respiratory Syndrome Virus.

A critical step in replication of positive-stranded RNA viruses is the assembly of replication and transcription complexes (RTC). We have recently mapped the nonstructural protein (nsp) interaction network of porcine reproductive and respiratory syndrome virus (PRRSV) and provided evidence by truncation mutagenesis that the recruitment of viral core replicase enzymes (nsp9 and nsp10) to membrane proteins (nsp2, nsp3, nsp5, and nsp12) is subject to regulation. Here, we went further to discover an intramolecular switch within the helicase nsp10 that controls its interaction with the membrane-associated protein nsp12.
