The small RNA RsmZ is known to sequester proteins that repress translation in bacteria. A study published in Nature this month (May 14), uncovered the sponge-like ability of the RNA to soak up multiple repressor proteins.
According to the news report, the researchers used NMR to determine the structure of the RNA bound to a single repressor protein. Pairing that with electron paramagnetic resonance spectroscopy, the researchers ascertained the complete structure of the complex, which illustrated how the various arms of the RNA act in concert.
