zinc ion transmembrane transporter activity obsolete zinc, cadmium, cobalt, nickel, lead-efflux ATPase activity true GO:0008552 zinc, cadmium, cobalt, nickel, lead-efflux ATPase activity OBSOLETE. Catalysis of the reaction: Me2+(in) + ATP = Me2+(out) + ADP + phosphate, where Me is Zn2+, Cd2+, Co2+, Ni2+ or Pb2+. This term was made obsolete because it represents more than one molecular function. molecular_function cadmium ion transmembrane transporter activity cobalt ion transmembrane transporter activity lead ion transmembrane transporter activity nickel cation transmembrane transporter activity P-type ion transporter activity
