Stimulation of stop codon readthrough: frequent presence of an extended 3′ RNA structural element 2011-04-27 .txt text/plain 7256 324 50 With respect to the non-structural polyprotein, SINV and Aura virus (AURAV) form a separate clade from VEEV, WEEV and EEEV but, again, the conservation analysis revealed striking tandem conservation peaks 3 0 of the RT site ( Figure 1B ) and, again, the conservation peaks corresponded to sequences with the potential to base pair to form an RNA structure-this time comprising an 11 bp stem with a 1 nt asymmetric 3 0 bulge, a 12 nt 'spacer' from the RT stop codon, and a 154 nt 'loop' region ( Figure 2 ). The potential to form an extended stemloop structure 3 0 -adjacent to a RT stop codon-phylogenetically conserved and supported by a pair of peaks in synonymous site conservation-was also found in a number of plant virus RT cases, for example, in the replicase gene in the genera (Figures 3 and 4) . ./cache/cord-000435-2u49b7xo.txt ./txt/cord-000435-2u49b7xo.txt
