CC   -!- FUNCTION: Zinc transporter. Acts as a Zn(2+):proton symporter, which
CC       likely mediates zinc ion uptake. {ECO:0000255|HAMAP-Rule:MF_01565}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=H(+)(out) + Zn(2+)(out) = H(+)(in) + Zn(2+)(in);
CC         Xref=Rhea:RHEA:71195, ChEBI:CHEBI:15378, ChEBI:CHEBI:29105;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01565};
CC       PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:71196;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01565};
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC       Rule:MF_01565}; Multi-pass membrane protein {ECO:0000255|HAMAP-
CC       Rule:MF_01565}.
CC   -!- SIMILARITY: Belongs to the CorA metal ion transporter (MIT) (TC 1.A.35)
CC       family. {ECO:0000255|HAMAP-Rule:MF_01565}.
