||P.59 right column bottom paragraph:"Kinesin walks in a ‘hand-over-hand’ manner [e.g. [ref 10]], with each head taking alternating 16 nm ‘steps’ (Figure 2a) [primary source]. This mechanism requires tight coupling between the biochemical cycles of both heads so that the front head remains bound to the MT [microtubule] while the rear head detaches. A conformational change in the front head then moves the detached head forward. This conformational change most probably occurs in a ∼13 aa peptide that links the motor domain to the coiled-coil stalk called the neck linker (Figure 1a) [ref 21]."
