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 Hyphomicrobiales (formerly known as 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. Flg-Rhizobiales RNA
