Flg Rhizobiales RNA motif

The flg-Rhizobiales RNA motif is an RNA structure that is conserved in certain bacteria. All known flg-Rhizobiales RNAs are located in the presumptive 5' untranslated regions of operons that contain genes whose functions relate to the creation of flagellar basal bodies. The flg-Rhizobiales RNAs are restricted to the Rhizobiales, an order of alphaproteobacteria, although only some Rhizobiales bacterial are predicted to use flg-Rhizobiales RNAs. The exact function of these RNAs is unknown, although it is hypothesized that they have a cis-regulatory function in controlling expression of the downstream operons.
