...ng,'' he noted. ''Recent evidence points toward an inchworm model, where one head reaches out and grabs the microtubule, while the other head just comes along for the ride. In any case, we're staying neutral.''

...re are two competing models for how kinesin walks: inchworm and hand-over-hand," Block said. "In the inchworm model, the leading head holds onto the microtubule, and the trailing head moves up to meet it. The s...Molecular motor myosin VI moves 'hand over hand,' researchers say
...rms alternate in the lead. The other model is the inchworm model in which one arm always leads." To examine t... the protein used a hand-over-hand mechanism or an inchworm mechanism for movement. "The average step size for the myosin VI arm was approximately 60 nanometer...
