Abstract
Theory and experiment have established that F-actin filaments are strongly attached to the intracellular parasites (such as Listeria) they propel with ``comet tails''. We consider the implications of these observations for propulsion. By calculating the motion produced in various models of attachment and comparing to experiment we demonstrate that the attachment must be sliding rather than hinged. By modeling experiments on ActA-coated spheres we draw conclusions regarding the interaction between F-actin and their surfaces that may also be applicable to living systems.
