FUNCTIONCatalyzes the formation of L-homocysteine from O-succinyl-L- homoserine (OSHS) and hydrogen sulfide.
CATALYTIC ACTIVITY Reaction=hydrogen sulfide + O-succinyl-L-homoserine = L-homocysteine + succinate; Xref=Rhea:RHEA:27826, ChEBI:CHEBI:29919, ChEBI:CHEBI:30031, ChEBI:CHEBI:57661, ChEBI:CHEBI:58199;
COFACTOR Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
PATHWAYAmino-acid biosynthesis; L-methionine biosynthesis via de novo pathway; L-homocysteine from O-succinyl-L-homoserine: step 1/1.
SUBUNITHomotetramer.
SIMILARITYBelongs to the trans-sulfuration enzymes family. MetZ subfamily.
