Reaction: ATP + H2O + polyamineout = ADP + phosphate + polyaminein
Systematic name: ATP phosphohydrolase (polyamine-importing)
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 putrescine and spermidine.
