The enzyme studied by Professor Drąg and his team is a so-called protease, dubbed SARS-CoV-2 Mpro.
Protease enzymes are responsible for cutting down proteins into smaller particles.
In the case of the coronavirus, the enzyme cuts through proteins and allows the pathogen to survive.
Professor Drąg said: “It allows it to survive. Stopping the enzyme immediately causes the virus to die.
“If we were to develop a drug that could inhibit the enzyme, then we are effectively killing the coronavirus.
