The Bacteroidales-2 RNA motif is a conserved RNA structure that was discovered by bioinformatics.[1] Bacteroidales-2 motifs are found in Bacteroidales. Bacteroidales-2 RNAs likely function in trans as sRNAs.
Bacteroidales-2 RNAs are relatively large compared to most other bacterial sRNAs, averaging just over 400 nucleotides. Despite this large size, Bacteriodales-2 RNAs exhibit a relatively simple secondary structure, being composed mainly of hairpins.
Bacteroidales-2 RNAs often occur adjacent to large regions that do not appear to encode proteins. A possible weak association with Mu-like phages was proposed. The hairpin on the 3' end of the Bacteroidales-2 motif might function as a Rho-independent transcription terminator.
