EC 5.6.1.4 Details

show Brenda entry

EC number

5.6.1.4

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)

Comment

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 5.6.1.3, plus-end-directed kinesin ATPase, but the organization of the different domains differs, resulting in movement in the opposite direction along the microtubules.

History

created 2000 as 3.6.4.5, transferred 2018 to EC 5.6.1.4
