IntEnz Enzyme Nomenclature


Accepted name:
ABC-type α-factor-pheromone transporter
Other names:
α-factor-transporting ATPase
α-factor-pheromone transporting ATPase
Systematic name:
ATP phosphohydrolase (ABC-type, α-factor-exporting)



An ATP-binding cassette (ABC) type transporter, characterized by the presence of two similar ATP-binding domains/proteins and two integral membrane domains/proteins. Does not undergo phosphorylation during the transport process. A yeast enzyme that exports the α-factor sex pheromone. Formerly EC
