CC   -!- FUNCTION: This regulatory protein, when combined with SAM (S-
CC       adenosylmethionine) represses the expression of the methionine regulon
CC       and of enzymes involved in SAM synthesis. {ECO:0000255|HAMAP-
CC       Rule:MF_00744}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_00744}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00744}.
CC   -!- DOMAIN: Does not bind DNA by a helix-turn-helix motif.
CC   -!- SIMILARITY: Belongs to the MetJ family. {ECO:0000255|HAMAP-
CC       Rule:MF_00744}.
