Chlorobi-RRM RNA motif

The Chlorobi-RRM RNA motif is a conserved RNA structure identified by bioinformatics.[1] It is found within bacteria in the phylum Chlorobiota (formerly Chlorobi), and is exclusively detected in the presumed 5' untranslated regions (5' UTRs) of genes that encode putative RNA-binding proteins. Since many RNA-binding proteins regulate their own expression in a feedback mechanism by binding or acting up their 5' UTR, it was proposed that the Chlorobi-RRM is a component in an analogous feedback mechanism. Structurally, the motif consists of two stem-loops, the second of which might function as a rho-independent transcription terminator.
