begins with the trailing head releasing inorganic phosphate (Pi) derived from the hydrolysis of ATP.
* The trailing head detaches from the microtubule and rotates into its rightward displaced unbound state.
* The leading head binds ATP which causes the neck linker to dock to it, which moves the trailing head around the leading head into a position further along the microtubule in the direction of travel. The trailing head remains unbound.
* The ATP in the leading head is hydrolyzed.
* The trailing head releases its ADP and
