"WebOct 20, 2009 · Kinesin is a processive motor, making hundreds of steps before detaching from the MT. It is thought that processivity is achieved by keeping the ATP-hydrolysis cycles of both motor domains out-of-phase, by a gating mechanism, operated via tension on the linkage between the two motor domains ( 6, 7 ).

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. 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.
