Structure of the Respiratory Syncytial Virus Polymerase Complex

Abstract : Graphical Abstract Highlights d Cryo-EM structure of RSV L bound by tetrameric RSV P solved to 3.2 Å d P tetramer adopts an asymmetric tentacular arrangement when bound to L d L priming loop adopts elongation-compatible state without PRNTase-RdRp separation d Structure rationalizes escape from small-molecule antivirals In Brief Respiratory syncytial virus (RSV) remains a leading cause of bronchiolitis and hospitalization, especially of infants. Gilman et al. present a 3.2-Å cryo-EM structure of the RSV L polymerase in complex with the P phosphoprotein-components of the core viral replication machinery that represent an attractive target for the development of therapeutic agents.
