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}.
CC   -!- SIMILARITY: Belongs to the fosfomycin resistance protein family. FosB
CC       subfamily. {ECO:0000255|HAMAP-Rule:MF_01512}.
