The authors present the full-length structure of the polymerase (L protein) from the severe fever with thrombocytopenia syndrome virus (SFTSV)—a segmented, negative-stranded RNA virus. The structure reveals important details with implications for the understanding of viral transcription and replication, and provides information on the organization of the polymerase core domain, entrance and exit tunnels, as well as the cap-binding and endonuclease domains.
