title: TrwB: an F(1)-ATPase-like molecular motor involved in DNA transport during bacterial conjugation.
abstract: The mechanism by which TrwB acts as a DNA transporter in bacterial conjugation is analyzed. Based on a parallelism between TrwB and F(1)-ATPase, TrwB would use the energy derived from ATP hydrolysis to pump DNA through its central channel, in a manner similar to that used by F(1)-ATPase to produce a rotary movement of the central gamma-subunit.
