DEAD-box RNA helicases are enzymes that have a role in several important biologicalprocesses, such as nucleic acids degradation or stabilization, assembly of riboproteiccomplexes and ribosome biogenesis. Caulobacter crescentus is an oligotrophic bacteriumbelonging to the ±-proteobacteria group, which has four genes encoding RNA helicases of theDEAD-box family. Previous work has shown that…
