Minus-end-directed kinesin ATPase

Minus-end-directed kinesin ATPase (EC 3.6.4.5) is an enzyme with systematic name kinesin ATP phosphohydrolase (minus-end-directed).^[1]^[2]^[3] This enzyme catalyses the following chemical reaction

ATP + H₂O

\rightleftharpoons

ADP + phosphate

This enzyme catalyses movement towards the minus end of microtubules.
