The poorly studied picornavirus, human parechovirus 3 (HPeV3) causes neonatal
sepsis with no therapies available. Our 4.3-Å resolution structure of HPeV3 on
its own and at 15?Å resolution in complex with human monoclonal antibody Fabs
demonstrates the expected picornavirus capsid structure with three distinct
features. First, 25% of the HPeV3 RNA genome in 60 sites is highly ordered as
confirmed by asymmetric reconstruction, and interacts with conserved regions of
the capsid proteins VP1 and VP3. Second, the VP0 N terminus stabilizes the capsid
inner surface, in contrast to other picornaviruses where on expulsion as VP4, it
forms an RNA translocation channel. Last, VP1's hydrophobic pocket, the binding
site for the antipicornaviral drug, pleconaril, is blocked and thus inappropriate
for antiviral development. Together, these results suggest a direction for
development of neutralizing antibodies, antiviral drugs based on targeting the
RNA-protein interactions and dissection of virus assembly on the basis of RNA
nucleation.
