Plus-end-directed kinesin ATPase

Plus-end-directed kinesin ATPase (EC 3.6.4.4, kinesin) is an enzyme with systematic name kinesin ATP phosphohydrolase (plus-end-directed).^[1]^[2]^[3] This enzyme catalyses the following chemical reaction

ATP + H₂O

\rightleftharpoons

ADP + phosphate

This enzyme also hydrolyses GTP.
