Mechanics of the kinesin step
Webnumber of models to explain kinesin motion have since been entertained, which predict that the 8-nm step should be com-posed of substeps of one form or another. Substeps are by no means unreasonable to contemplate, for a variety of plausible reasons (see below). Two studies have claimed to identify substeps within the kinesin cycle. WebFeb 26, 2007 · The subsequent discovery of “limping” in kinesin, where the average kinetics of every other step switch between a faster and a slower stepping phase, proved that kinesin dimers advance through an asymmetric HoH motion, and that this motion is inconsistent with either the inchworm or symmetric HoH patterns.
