CC -!- FUNCTION: Metallothiol transferase which confers resistance to
CC fosfomycin by catalyzing the addition of a thiol cofactor to
CC fosfomycin. L-cysteine is probably the physiological thiol donor.
CC {ECO:0000255|HAMAP-Rule:MF_01512}.
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01512};
CC -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_01512}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01512}.
