CC ChEBI:CHEBI:57476, ChEBI:CHEBI:57661; EC=2.3.1.46;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00295};
CC -!- PATHWAY: Amino-acid biosynthesis; L-methionine biosynthesis via de novo
CC pathway; O-succinyl-L-homoserine from L-homoserine: step 1/1.
CC {ECO:0000255|HAMAP-Rule:MF_00295}.
CC -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_00295}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00295}.
