Ribosome dynamics at the conserved PGP motif governs 2A peptide-bond-skipping efficiency
Abstract Viral 2A oligopeptides drive an unusual ribosome recoding event in which peptide-bond formation fails at a conserved PG↓P motif, producing two discrete proteins without canonical termination. Despite decades of study, the molecular basis of 2A-mediated peptide-bond skipping remains poorly understood. Here, we...
