Structural basis of Nipah virus RNA synthesis.

ABSTRACT: Nipah virus (NiV) is a non-segmented negative-strand RNA virus (nsNSV) with high pandemic potential, as it frequently causes zoonotic outbreaks and can be transmitted from human to human. Its RNA-dependent RNA polymerase (RdRp) complex, consisting of the L and P proteins, carries out viral genome replication and transcription and is therefore an attractive drug target. Here, we report cryo-EM structures of the NiV polymerase complex in the apo and in an early elongation state with RNA and incoming substrate bound. The structure of the apo enzyme reveals the architecture of the NiV L-P complex, which shows a high degree of similarity to other nsNSV polymerase complexes. The structure of the RNA-bound NiV L-P complex shows how the enzyme interacts with template and product RNA during early R
