Fig 5. Preferred target sites identified in sigF are positioned within stems and loops.

(A) Four major stem-loop secondary structures taken from the predicted secondary structure of sigF RNA and (B) predicted secondary structure of 5’5 RNA and the preferred target sequence [11]. The stem loops are coloured by base pair probability and the preferred target sequences are highlighted with black circles and white text. RNA secondary structure was modelled by RNAfold [21].
