DNA packaging: a new class of molecular motors

Curr Biol. 2002 Feb 5;12(3):R96-8. doi: 10.1016/s0960-9822(02)00670-x.


DNA is packaged into preformed bacteriophage capsids to liquid crystalline density by the action of a portal protein complex. Single molecule packaging studies indicate that this is a new and extremely powerful class of molecular motors.
