IMES-3 RNA motif

The IMES-3 RNA motif is a conserved RNA structure that was identified based on metagenomics and bioinformatics,[1] and the underlying RNA sequences were identified independently by an earlier study.

[2] These RNAs are present in environmental sequences, and as of 2009 are not known to be present in any cultivated species.

IMES-3 RNAs are abundant in comparison to ribosomes[1] in RNAs sampled from the Pacific Ocean.
