CC -!- FUNCTION: Catalyzes the hydrolysis of N-succinyl-L,L-diaminopimelic
CC acid (SDAP), forming succinate and LL-2,6-diaminoheptanedioate (DAP),
CC an intermediate involved in the bacterial biosynthesis of lysine and
CC meso-diaminopimelic acid, an essential component of bacterial cell
CC walls. {ECO:0000255|HAMAP-Rule:MF_01690}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H2O + N-succinyl-(2S,6S)-2,6-diaminoheptanedioate = (2S,6S)-
CC 2,6-diaminoheptanedioate + succinate; Xref=Rhea:RHEA:22608,
CC ChEBI:CHEBI:15377, ChEBI:CHEBI:30031, ChEBI:CHEBI:57609,
CC ChEBI:CHEBI:58087; EC=3.5.1.18; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_01690};
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01690};
CC Name=Co(2+); Xref=ChEBI:CHEBI:48828;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01690};
CC Note=Binds 2 Zn(2+) or Co(2+) ions per subunit. {ECO:0000255|HAMAP-
CC Rule:MF_01690};
CC -!- PATHWAY: Amino-acid biosynthesis; L-lysine biosynthesis via DAP
CC pathway; LL-2,6-diaminopimelate from (S)-tetrahydrodipicolinate
CC (succinylase route): step 3/3. {ECO:0000255|HAMAP-Rule:MF_01690}.
CC -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_01690}.
CC -!- SIMILARITY: Belongs to the peptidase M20A family. DapE subfamily.
CC {ECO:0000255|HAMAP-Rule:MF_01690}.
