EC 7.2.2.2     
Accepted name: ABC-type Cd2+ transporter
Reaction: ATP + H2O + Cd2+[side 1] = ADP + phosphate + Cd2+[side 2]
Other name(s): cadmium-transporting ATPase (ambiguous); ABC-type cadmium-transporter
Systematic name: ATP phosphohydrolase (ABC-type, heavy-metal-exporting)
Comments: 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 some heavy metals, especially Cd2+, from the cytosol into the vacuole.
