Experimental test of connector rotation during DNA packaging into bacteriophage phi29 capsids [PDF]

, 2007
The bacteriophage phi29 generates large forces to compact its double-stranded DNA genome into a protein capsid by means of a portal motor complex. Several mechanical models for the generation of these high forces by the motor complex predict coupling of ...
