CC -!- FUNCTION: Transfers a succinyl group from succinyl-CoA to L-homoserine,
CC forming succinyl-L-homoserine. {ECO:0000256|HAMAP-Rule:MF_00296}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=L-homoserine + succinyl-CoA = CoA + O-succinyl-L-homoserine;
CC Xref=Rhea:RHEA:22008, ChEBI:CHEBI:57287, ChEBI:CHEBI:57292,
CC ChEBI:CHEBI:57476, ChEBI:CHEBI:57661; EC=2.3.1.46;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_00296};
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:0000256|HAMAP-Rule:MF_00296}.
CC -!- SUBUNIT: Homodimer. {ECO:0000256|HAMAP-Rule:MF_00296}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00296}.
CC -!- SIMILARITY: Belongs to the AB hydrolase superfamily. MetX family.
CC {ECO:0000256|HAMAP-Rule:MF_00296}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_00296}.
