| FUNCTION | Divalent metal cation transporter which exports Zn(2+), Cd(2+) and possibly Fe(2+). May be involved in zinc and iron detoxification by efflux. |
| CATALYTIC ACTIVITY | Reaction=Zn(2+)(in) + H(+)(out) = Zn(2+)(out) + H(+)(in); Xref=Rhea:RHEA:28839, ChEBI:CHEBI:15378, ChEBI:CHEBI:29105; |
| CATALYTIC ACTIVITY | Reaction=Cd(2+)(in) + H(+)(out) = Cd(2+)(out) + H(+)(in); Xref=Rhea:RHEA:28739, ChEBI:CHEBI:15378, ChEBI:CHEBI:48775; |
| CATALYTIC ACTIVITY | Reaction=Fe(2+)(in) + H(+)(out) = Fe(2+)(out) + H(+)(in); Xref=Rhea:RHEA:29439, ChEBI:CHEBI:15378, ChEBI:CHEBI:29033; |
| SUBUNIT | Homodimer. |
| SUBCELLULAR LOCATION | Cell inner membrane; Multi-pass membrane protein. |
| SIMILARITY | Belongs to the cation diffusion facilitator (CDF) transporter (TC 2.A.4) family. FieF subfamily. |
