FIG 1.
The regulatory elements of the agnK12 5′ region. (A) Schematic representation of the agnK12 regulatory region from positions −35 to +223 showing the OxyR binding region, methylation sites, ORF, and terminator, as indicated. Two potential translation initiation codons (ATG-1 and ATG-2) are also shown. (B) DNA sequence of the agnK12 5′ region from positions +1 to +275. Dam target sequences (GATC) are in boldface type. The agnK12 terminator sequence and the two translational start sites ATG-1 and ATG-2 at positions +67 and +223 are underlined. (C) Predicted secondary structure of the region from positions 162 to 194 of the agnK12 leader RNA (see Fig. SA1 in the supplemental material).
