A Phylogenetically Conserved Hairpin-Type 3′ Untranslated Region Pseudoknot Functions in Coronavirus RNA Replication
1 Oct 1999
Abstract excerpt
Secondary and tertiary structures in the 3' untranslated region (UTR) of plus-strand RNA viruses have been postulated to function as control elements in RNA replication, transcription, and translation. Here we describe a 54-nucleotide (nt) hairpin-type pseudoknot within the 288-nt 3' UTR of the bovine coronavirus genome and show by mutational analysis of both stems that the pseudoknotted structure is required for...
