EC 5.6.1.1     
Accepted name: microtubule-severing ATPase
Reaction: n ATP + n H2O + a microtubule = n ADP + n phosphate + (n+1) α/β tubulin heterodimers
Other name(s): katanin
Systematic name: ATP phosphohydrolase (tubulin-dimerizing)
Comments: A member of the AAA-ATPase family, active in splitting microtubules into tubulin dimers in the centrosome.
