(A) Plot of all predicted LRIs with (74) found in the HCV alignment of 106 sequences. The
outer circle represents the genome. The histogram represents the number of LRIs per
alignment position. High reactive genome positions can be found in the 5′/3′ UTR and the
coding region of the core gene C. The inner circle shows all predicted
interactions between all genome positions. Gray—all new LRIs; black—LRIs corresponding
to B and C. The plot was created with Circos (Krzywinski et al., 2009). (B) Experimentally
verified LRIs, which can be predicted by LRIscan, named SLIIId-5BSL3.2 (Romero-López and Berzal-Herranz, 2009, 2012), 5BSL2-5BSL3.2 (Romero-López et al., 2014; Tuplin et al., 2012),
5BSL3.2-3′SLII (Friebe et al.,
2005) and 5′ UTR-core (Beguiristain
et al., 2005; Honda
et al., 1999). (C) Highly interesting new LRIs
predicted by LRIscan. In a former study, we suggested that LRI 2e could
be a seed interaction for a HCV genome circularization (Fricke et al., 2015). A complete list
including all predicted LRIs can be found at the supplementary page. Colors are used to
indicate conserved base-pairs: from red (no variation of a base-pair within the
alignment) to purple (all six base-pair types are found); from dark (all sequences
contain this base-pair) to light colors (1 or 2 sequences are unable to form this
base-pair). Compensatory mutations are marked by a circle around the variable base(s)
