Distal protein-protein interactions contribute to nirmatrelvir resistance by Eric M. Lewandowski, Xiujun Zhang, Haozhou Tan, Aiden Jaskolka-Brown, Navita Kohaal, Aliaksandra Frazier, Jesper J. Madsen, Lian M. C. Jacobs, Jun Wang, Yu Chen

“…To probe the role of the non-active site mutations in fitness rescue, here we use an Mpro triple mutant (L50F/E166A/L167F) that confers nirmatrelvir drug resistance with a viral fitness level similar to the wild-type. By comparing peptide and full-length Mpro protein as substrates, we demonstrate that the binding of Mpro substrate involves more than residues in the active site. …”
