Schematic showing the sequential revolution motion in translocating dsDNA. (A) Revolution of dsDNA inside the ATPase hexameric ring. (Adapted from reference 12.) (B) Diagram of cryo-EM results showing offset of dsDNA in the channel of the bacteriophage T7 DNA-packaging motor. The dsDNA did not appear in the center of the channel; instead, the dsDNA tilted toward the wall of the motor channel. (Adapted from reference 131 with permission of the publisher.) (C) Revolution of dsDNA along the 12 subunits of the connector channel. (Adapted from reference 12.)
