Figure 2. Secondary structure of O. lunifer rrnS and substitution patterns in the rrnS ALN.

Figure 2

Each helix is numbered progressively from the 5’ to the 3’ end together with the first nucleotide belonging to the helix itself. Domains are labelled with Roman numerals. Tertiary structures are denoted by boxed bases joined by solid lines. Watson-Crick pairs are joined by dashes. GT pairs are joined by a blue dot, while other non-canonical pairs are connected by a red dot. Conserved position, position invariable in the rrnS ALN. Variable position, position not conserved in the rrnS ALN.
