protein translocation chaperone activity
Binding to the exposed unfolded portion of a polypeptide as it emerges from a membrane translocation channel/pore to drive its unidirectional transport across a membrane. Iterative cycles of ATP-dependent binding/rebinding by the chaperone prevents back sliding and drive vectorial transport.
