  • PubMed Abstract: 

    An outbreak of mpox virus in May 2022 has spread over 110 nonpandemic regions in the world, posing a great threat to global health. Mpox virus E5, a helicase-primase, plays an essential role in DNA replication, but the molecular mechanisms are elusive. Here, we report seven structures of mpox virus E5 in a double hexamer (DH) and six in single hexamer in different conformations, indicating a rotation mechanism for helicase and a coupling action for primase. The DH is formed through the interface of zinc-binding domains, and the central channel density indicates potential double-stranded DNA (dsDNA), which helps to identify dsDNA binding residues Arg 249 , Lys 286 , Lys 315 , and Lys 317 . Our work is important not only for understanding poxviral DNA replication but also for the development of novel therapeutics for serious poxviral infections including smallpox virus and mpox virus.
