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.
Catalytic activity RHEA:22608: H2O + N-succinyl-(2S,6S)-2,6-diaminoheptanedioate = (2S,6S)-2,6-diaminoheptanedioate + succinate
Cofactor Zn(2+)
Note: Binds 1 Zn(2+) ion per subunit.
Note: Binds 1 Co(2+) ion per subunit.
Pathway Amino-acid biosynthesis; L-lysine biosynthesis via DAP pathway; LL-2,6-diaminopimelate from (S)-tetrahydrodipicolinate (succinylase route): step 3/3.
Subunit Homodimer.
Similarity Belongs to the peptidase M20A family. DapE subfamily.
