General annotation (Comments)

Function	Catalyzes the hydrolysis of N-succinyl-L,L-diaminopimelic acid (SDAP), forming succinate and LL-2,6-diaminoheptanedioate (DAP), an intermediate involved in the bacterial biosynthesis of lysine and meso-diaminopimelic acid, an essential component of bacterial cell walls By similarity.
Catalytic activity	N-succinyl-LL-2,6-diaminoheptanedioate + H2O = succinate + LL-2,6-diaminoheptanedioate.
Cofactor	Binds 1 Zn2+ ion per subunit By similarity. Binds 1 Co2+ ion per subunit By similarity.
Pathway	Amino-acid biosynthesis; L-lysine biosynthesis via DAP pathway; LL-diaminopimelate from tetrahydrodipicolinate (succinylase route): step 3/3.
Subunit structure	Homodimer By similarity.
Sequence similarities	Belongs to the peptidase M20A family. DapE subfamily.
