Figure 2

Two types of ASCE hexameric dsDNA motors. (A) Unidirectional motors represented by phage φ29 gp16 using a revolution mechanism with a power stroke between subunits through an entropy-DNA affinity switch to push dsDNA into the page head without rotation of DNA and the motor. (B) Bidirectional motors represented by bacterial FtsK employing the similar revolution mechanism. (Created by artist Grant Cochran).
