Primer extension analysis of RNPs containing S12 variants. Sequencing gel of 16S rRNA in the following reactions: untreated 16S rRNA (lane 1); dimethyl sulfate treated 16S rRNA (lanes 2,10); dimethyl sulfate-treated minimal complex (S4, S7, S8, S15, S16, S17, S20, 16S rRNA) (lanes 3,9); dimethyl sulfate-treated minimal complex with S12WT (lane 4), S12 full-length (lane 5), S12▵10N (lane 6), S12▵15N (lane 7), and S12▵27N (lane 8). A and G are sequencing lanes. Bars indicate changes in methylation patterns compared with complexes lacking S12 (lanes 3,9). The primers utilized in A, B, and C are 232, 683, and 1046, respectively.
