EC 3.6.3.32     
Accepted name: quaternary-amine-transporting ATPase
Reaction: ATP + H2O + quaternary amineout = ADP + phosphate + quaternary aminein
Systematic name: ATP phosphohydrolase (quaternary-amine-importing)
Comments: ABC-type (ATP-binding cassette-type) ATPase, characterized by the presence of two similar ATP-binding domains. Does not undergo phosphorylation during the transport process. A bacterial enzyme that imports betaine and glycine.
