DNA topoisomerases: single gyrase caught in the act

Curr Biol. 2006 Mar 21;16(6):R204-6. doi: 10.1016/j.cub.2006.02.029.


A recent study has analysed the action of bacterial DNA gyrase on a single substrate DNA molecule, discriminating the initial DNA wrapping and subsequent supercoiling steps in the reaction cycle.
