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         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}.
