How the COVID-19 virus copies its genetic code and how to block it

Kinetic and structural basis for SARS-CoV-2 RNA-dependent RNA polymerase specificity and inhibition

NIH-funded research University of Texas at Austin · NIH-11160593

Researchers are mapping how the coronavirus's copying enzyme works so scientists can design safer, more effective antiviral drugs for people with COVID-19.

What this research studies

This project looks closely at the SARS‑CoV‑2 RNA‑dependent RNA polymerase (the viral enzyme that copies the virus's RNA) using detailed biochemical and structural experiments. The team will measure how the enzyme adds and removes nucleotide building blocks using rapid single‑turnover kinetic tests and determine atomic structures to see how drugs fit into the enzyme. That information will guide design and testing of nucleotide‑analog inhibitors related to drugs like remdesivir. The work is done in a laboratory setting at the University of Texas at Austin to support development of better antivirals for current and future coronavirus strains.

Who could benefit from this research

Good fit: People with active or recent SARS‑CoV‑2 (COVID‑19) infection or those at high risk of severe COVID‑19 would be the most likely to benefit from therapies developed using these findings.

Not a fit: Individuals with illnesses unrelated to coronaviruses or those seeking immediate clinical treatment are unlikely to receive direct benefit from this laboratory research itself.

Why it matters

Potential benefit: If successful, this work could lead to more effective and less toxic antiviral medicines to treat COVID‑19 and future coronavirus infections.

How similar studies have performed: Related approaches have produced effective polymerase inhibitors for HIV and hepatitis C, and remdesivir has shown some clinical promise against COVID‑19, but targeted SARS‑CoV‑2 polymerase inhibitors remain under active development.
