1. Possible secondary structure of the S. enterica prs leader.
Possible secondary structure of the S. enterica prs leader. The sequence ranges from nucleotide 1, indicated by 5′, to nucleotide 417, which is immediately followed by the initiator codon-specifying guanylate-uridylate-guanylate triplet and is indicated by 3′ (45). The ΔG of the structure is −540 kJ mol−1. The leader prs sequences of S. enterica and E. coli are identical except for the framed sequence, which is present only in the S. enterica prs leader. The nucleotides circled in red represent a possible leader peptide, and the red arrows point to the nucleotides of a possible Shine-Dalgarno sequence. Possible leader peptide amino sequences are indicated for E. coli and S. enterica. Identical amino acid residues of the two possible leader peptides are underlined.
