CC -!- FUNCTION: Divalent metal cation transporter which exports Zn(2+),
CC Cd(2+) and possibly Fe(2+). May be involved in zinc and iron
CC detoxification by efflux. {ECO:0000255|HAMAP-Rule:MF_01425}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H(+)(out) + Zn(2+)(in) = H(+)(in) + Zn(2+)(out);
CC Xref=Rhea:RHEA:28839, ChEBI:CHEBI:15378, ChEBI:CHEBI:29105;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01425};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Cd(2+)(in) + H(+)(out) = Cd(2+)(out) + H(+)(in);
CC Xref=Rhea:RHEA:28739, ChEBI:CHEBI:15378, ChEBI:CHEBI:48775;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01425};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Fe(2+)(in) + H(+)(out) = Fe(2+)(out) + H(+)(in);
CC Xref=Rhea:RHEA:29439, ChEBI:CHEBI:15378, ChEBI:CHEBI:29033;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01425};
CC -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_01425}.
CC -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC Rule:MF_01425}; Multi-pass membrane protein {ECO:0000255|HAMAP-
CC Rule:MF_01425}.
CC -!- SIMILARITY: Belongs to the cation diffusion facilitator (CDF)
CC transporter (TC 2.A.4) family. FieF subfamily. {ECO:0000255|HAMAP-
CC Rule:MF_01425}.
