  • PubMed Abstract: 

    The transcription and replication of the severe acute respiratory syndrome (SARS) coronavirus (SARS-CoV) is regulated by specific viral genome sequences within 5'- and 3'-untranslated regions (5'-UTR and 3'-UTR). Here we report the solution structure of 5'-UTR derived stem-loop 2 (SL2) of SARS-CoV determined by NMR spectroscopy. The highly conserved pentaloop of SL2 is stacked on 5-bp stem and adopts a canonical CUYG tetraloop fold with the 3' nucleotide (U51) flipped out of the stack. The significance of this structure in the context of a previous mutagenesis analysis of SL2 function in replication of the related group 2 coronavirus, mouse hepatitis virus, is discussed.
