Here, we identified the first promoter element for RNA synthesis described in a flavivirus. Using dengue virus as a model, we found that the viral RdRp discriminates the viral RNA by specific recognition of a 5 element named SLA. We demonstrated that RNA–RNA interactions between 5 and 3 end sequences of the viral genome enhance dengue virus RNA synthesis only in the presence of an intact SLA. We propose a novel mechanism for minus-strand RNA synthesis in which the viral polymerase binds SLA at the 5 end of the genome and reaches the site of initiation TI - A 5′ RNA element promotes dengue virus RNA synthesis on a circular genome JF - Genes & Development DO - 10.1101/gad.1444206 DA - 2006-08-01 UR - https://www.deepdyve.com/lp/unpaywall/a-5-rna-element-promotes-dengue-virus-rna-synthesis-on-a-circular-LEIqSOSvjw DP - DeepDyve ER -
