CC   -!- FUNCTION: Guanidinium ion exporter. Couples guanidinium export to the
CC       proton motive force, exchanging one guanidinium ion for two protons.
CC       {ECO:0000250|UniProtKB:P69937}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane
CC       {ECO:0000250|UniProtKB:P69937}; Multi-pass membrane protein
CC       {ECO:0000250|UniProtKB:P69937}.
CC   -!- SIMILARITY: Belongs to the drug/metabolite transporter (DMT)
CC       superfamily. Small multidrug resistance (SMR) (TC 2.A.7.1) family.
CC       Gdx/SugE subfamily. {ECO:0000305}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=AAG59349.1; Type=Erroneous initiation; Evidence={ECO:0000305};
CC       Sequence=BAB38552.1; Type=Erroneous initiation; Evidence={ECO:0000305};
