Figure 3

Sequence variation between the 16 S rRNA 3′ minor domains of E. coli and Acidobacteria. A secondary structure map of the 3′ minor domain of E. coli (Eco) 16 S rRNA is shown. Functionally important nucleotides known to be involved in subunit assembly and association are indicated in red (see text for details). Nucleotide differences between acidobacterial (NS11) and Eco 16 S rRNA are indicated by arrows, with the nucleotides beside the arrows. The 3′ end nucleotide (A1542) is also indicated.
