    Flaviviruses are major emerging human pathogenic viruses that pose a persistent and growing menace to global health. They are enveloped single-stranded RNA viruses with positive polarity transmitted by arthropod vectors like mosquitoes or ticks, responsible for a significant and growing number of human deaths and illnesses. The 5'- and 3'-untranslated regions (UTRs) are highly structured and contain conserved cis-acting RNA elements that participate in viral translation, replication and host adaptation. Despite their role in fiaviviruses replication, few high-resolution structural studies have investigated the RNA elements required for viral replication. Here we report the NMR structures of stem-loop B from WNV and DENV4 viruses. Because this element is required for cyclization of the genome and the activity of the replicative viral enzymes, viral replication rates are sensitive to even small changes in these RNAs. Therefore, this work provides structural insight into a new drug target to reduce flavivirus replication rates.
