CC -!- FUNCTION: Proton-coupled chloride transporter. Functions as antiport
CC system and exchanges two chloride ions for 1 proton. Probably acts as
CC an electrical shunt for an outwardly-directed proton pump that is
CC linked to amino acid decarboxylation, as part of the extreme acid
CC resistance (XAR) response. {ECO:0000255|HAMAP-Rule:MF_01128}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=2 chloride(in) + H(+)(out) = 2 chloride(out) + H(+)(in);
CC Xref=Rhea:RHEA:29567, ChEBI:CHEBI:15378, ChEBI:CHEBI:17996;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01128};
CC -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_01128}.
CC -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC Rule:MF_01128}; Multi-pass membrane protein {ECO:0000255|HAMAP-
CC Rule:MF_01128}.
CC -!- SIMILARITY: Belongs to the chloride channel (TC 2.A.49) family. ClcA
CC subfamily. {ECO:0000255|HAMAP-Rule:MF_01128}.
