Group 2 sRNAs encode potential Group 1 antisense transcripts. Shown is an alignment for reverse and complemented ABUWs043 against the consensus sequence of Group 1 sRNAs (from alignment in Fig. S1). Structural predictions for ABUWs043 reveals a potential area of initial interaction with Group 1 transcripts via a series of exposed U residues (shown on the figure as red stars). These could potentially partner with an accessible region of exposed A nucleotides within members of Group 1 (marked with red arrows in Fig. S2).
