^a rRNA positions listed have an AAG motif in more than 50% of the bacterial sequences and are indicated in green on Figure 5. ^b The position number is the nucleotide at the 3’ loop end, at the loop-helix junction. ^c More detailed information is available at http://www.rna.icmb.utexas.edu/ANALYSIS/A-STORY/. ^d A, AA.AG@helix.ends; E, E loop; EL, E-like loop; GA, tandem G:A; U, U-turn (see Discussion). ^e Hairpin loop size (in nucleotides) and special characteristics: GNRA, tetraloops (Woese et al. 1990) occur in more than 70% of the bacterial rRNA sequences; *, unusually stable G:A or U:U first mismatch.
