Reaction: ATP + H2O + α-factorin = ADP + phosphate + α-factorout
Systematic name: ATP phosphohydrolase (α-factor-transporting)
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 yeast enzyme that exports the α-factor sex pheromone.
