A model for the torsional compression portal-DNA-grip-and-release packaging mechanism. A-C) Short nicked or other abnormal structure containing DNA substrates are released from the motor. D) Leader containing Y-DNA substrates are retained by the motor and are anchored in the procapsid in proximity to portal GFP fusions; and E) compression of the Y-stem B segment in the stalled complex is observed by FRET [88, 89]
