CC -!- FUNCTION: Catalyzes the formation of L-homocysteine from O-succinyl-L-
CC homoserine (OSHS) and hydrogen sulfide. {ECO:0000256|HAMAP-
CC Rule:MF_02056}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=hydrogen sulfide + O-succinyl-L-homoserine = L-homocysteine +
CC succinate; Xref=Rhea:RHEA:27826, ChEBI:CHEBI:29919,
CC ChEBI:CHEBI:30031, ChEBI:CHEBI:57661, ChEBI:CHEBI:58199;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_02056};
CC -!- COFACTOR:
CC Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
CC Evidence={ECO:0000256|ARBA:ARBA00001933,
CC ECO:0000256|HAMAP-Rule:MF_02056, ECO:0000256|RuleBase:RU362118};
CC -!- PATHWAY: Amino-acid biosynthesis; L-methionine biosynthesis via de novo
CC pathway; L-homocysteine from O-succinyl-L-homoserine: step 1/1.
CC {ECO:0000256|HAMAP-Rule:MF_02056}.
CC -!- SUBUNIT: Homotetramer. {ECO:0000256|HAMAP-Rule:MF_02056}.
CC -!- SIMILARITY: Belongs to the trans-sulfuration enzymes family. MetZ
CC subfamily. {ECO:0000256|HAMAP-Rule:MF_02056}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
