EC 3.6.3.33

Names

Accepted name:
vitamin B12-transporting ATPase
Systematic name:
ATP phosphohydrolase (vitamin B12-importing)

Reaction

Comments:

ABC-type (ATP-binding cassette-type) ATPase, characterised by the presence of two similar ATP-binding domains. Does not undergo phosphorylation during the transport process. A bacterial enzyme that imports cobalamin derivatives.
