Polynucleobacter-1 RNA motif

The Polynucleobacter-1 RNA motif is a conserved RNA structure that was identified by bioinformatics.[1] The RNA structure is predominantly located in genome sequences derived from DNA extracted from uncultivated marine samples. However it was also predicted in the genome of Polynucleobacter species QLW-P1DMWA-1, a kind of betaproteobacteria. The RNAs are often located near to a conserved gene that might be homologous to a gene found in a phage that infects cyanobacteria. However, it is unknown if the RNA is used by phages.
