UCSF scientists studying a key enzyme used by the virus that causes COVID-19 have identified chemical building blocks that might eventually be used to make an antiviral drug. The chemical fragments could bind to and disable the enzyme, called the “macro domain,” which is a crucial part of the SARS-CoV-2 virus’s ability to replicate in human cells. James Fraser discusses the finding from this research. Series: "Mini Medical School for the Public" [Health and Medicine] [Show ID: 36500]
