A guanine-flipping and sequestration mechanism for G-quadruplex unwinding by RecQ helicases
How G-quadruplexes (G4s) are resolved by helicases is still a matter of investigation. Here the authors provide mechanistic insight into G4s unwinding by presenting a crystal structure of resolved G4 DNA and the G4 binding domain of RecQ helicase from the bacterium Cronobacter sakazakii.
