FIG. 2.
(A) Secondary structures of S. thermodiastaticus JCM4840 16S rRNA regions used this study. Helix numbering is according to the nomenclature (4), and the base position numbering is according to that of S. ambofaciens (18). The arrow indicates the region used as a sequencing primer. Heterogeneous loci are indicated by the abbreviations given in Table 1, footnote a. (B) Secondary structures of helix 10 of two distinct sequences in S. thermodiastaticus 16S rRNAs. Bars and dots indicate Watson-Crick pairing and non-Watson-Crick pairing, respectively.
