Model for TubRZ-mediated segregation of pBtoxis. Snapshots of three successive stages of the process are shown. The TubR-pBtoxis complex associates with the treadmilling TubZ polymer via the interaction of TubR with the flexible C terminus of TubZ subunits. TubR bound to its cargo is handed over to successive TubZ subunits of the polymer in the (+) elongating direction. The bending of the TubZ filament at the cell pole exerts strain on the bound cargo, causing detachment of TubR-pBtoxis.
