GelfandMikhail RodionovDmitry A. 2014 <p>Regions 1–6 shown in yellow boxes are conserved sequences found in the multiple alignment of leader regions of 34 <i>metX</i> and <i>metZ</i> genes from β-proteobacteria (<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0113714#pone.0113714.s002" target="_blank">Figure S2</a>). In the consensus RNA sequence, N denotes any nucleotide, and M stands for A or C. Possible secondary structures formed by the interaction between the conserved regions are shown by yellow lines.</p>
