Remdesivir is a nucleoside analog approved by the US FDA for treatment of COVID-19. Here, we present a 3.9-Å-resolution cryo-EM reconstruction of a remdesivir-stalled RNA-dependent RNA polymerase complex, revealing full incorporation of 3 copies of remdesivir monophosphate (RMP) and a partially incorporated fourth RMP in the active site. The structure reveals that RMP blocks RNA translocation after incorporation of 3 bases following RMP, resulting in delayed chain termination, which can guide the rational design of improved antiviral drugs. Bravo et al. reveal the structural basis for remdesivir-induced stalling of the SARS-CoV-2 RNA-dependent RNA polymerase. The structure of the stalled RdRp shows that chain translocation is blocked by steric clashes between incorporated remdesivir and the polymerase.
