The Bacteroidales-1 RNA motif is a conserved RNA structure identified by bioinformatics.[1] It has been identified only in bacteria within the order (biology) Bacteroidales. Its presumed length is marked by a promoter on one end that conforms to an alternate consensus sequence that is common in the phylum Bacteroidota, and its 3′ end is indicated by predicted transcription terminators.[2] It is often located downstream of a gene that encodes the L20 ribosomal subunit, although it is unclear whether there is a functional reason underlying this apparent association.[1]
Bacteroidales-1 RNA motif has been reported as a 6S RNA homologue by a report of Bacteroides thetaiotaomicron transcriptome map.[3] The existence of small product RNAs (pRNAs) that rescue sequestered RNA polymerases, validated 6S RNA-mediated regulation of transcriptional activity.
