RNA remodeling by hexameric RNA helicases.

Abstract

The unwinding of RNA helices and the disruption of RNA-protein complexes are critical steps of cellular metabolism that are carried out by ubiquitous NTP-dependent enzymes named RNA helicases. Here, we review the structures, mechanisms, and biochemical properties of two RNA helicases known to adopt a homo-hexameric ring architecture: the P4 packaging motor… (More)
