    Snippet: Guanine quadruplexes (G4) structures in viral genome have a key role in modulating viruses’ biological activity. While several DNA G4 structures have been experimentally resolved, RNA G4s are definitely less explored. We report the first calculated G4 structure of the RG-1 RNA sequence of SARS-CoV-2 genome, obtained by using a multiscale approach combining quantum and classical molecular modelling and corroborated by the excellent agreement between the corresponding calculated and experimental
    Document: Guanine quadruplexes (G4) structures in viral genome have a key role in modulating viruses’ biological activity. While several DNA G4 structures have been experimentally resolved, RNA G4s are definitely less explored. We report the first calculated G4 structure of the RG-1 RNA sequence of SARS-CoV-2 genome, obtained by using a multiscale approach combining quantum and classical molecular modelling and corroborated by the excellent agreement between the corresponding calculated and experimental circular dichroism spectra. We prove the stability of RG-1 G4 arrangement as well as its interaction with G4 ligands potentially inhibiting viral protein translation.
