Among the 31 detected pseudoknots, the established −1 frameshift stimulating pseudoknot at the gag-pro junction [25, 43] is identified as the most stable pseudoknot as BioMed Research International 5 judged by the lowest calculated free energy of −33.7 kcal/mol (Table 1) . While pseudoknots were detected shortly downstream from the frame-shift or read-through sites in most of the viral sequences using the default ranges of stem and loop lengths, the default search did miss some known cases, such as the frameshift stimulator pseudoknot in human coronavirus 229E that has a 164 nt L2. "Rank" indicates the relative ranking (according to the calculated free energy of the stems) of the frameshift/readthrough stimulating pseudoknots among all possible pseudoknots detected within the full-length genomic RNAs.	./cache/cord-300944-c57impca.txt	./txt/cord-300944-c57impca.txt
