IUBMB Enzyme Nomenclature


Accepted name: minus-end-directed kinesin ATPase

Reaction: ATP + H2O + a kinesin associated with a microtubule at position n = ADP + phosphate + a kinesin associated with a microtubule at position n-1 (toward the minus end)

Other name(s): non-claret disjunctional; ncd (gene name)

Systematic name: kinesin ATP phosphohydrolase (minus-end-directed)

Comments: Kinesins are a family of motor proteins that move unidirectionally along microtubules as they hydrolyse ATP and are involved in organelle movement. This enzyme is similar to EC, plus-end-directed kinesin ATPase, but the organization of the different domains differs, resulting in movement in the opposite direction along the microtubules.
