succinyl-diaminopimelate desuccinylase activity

Catalysis of the reaction: N-succinyl-LL-2,6-diaminopimelate + H2O = LL-2,6-diaminopimelate + succinate.

diaminopimelate epimerase activity

Catalysis of the reaction: LL-2,6-diaminopimelate = meso-2,6-diaminopimelate.

L,L-diaminopimelate aminotransferase activity

Catalysis of the reaction: 2-oxoglutarate + LL-2,6-diaminopimelate = (S)-2,3,4,5-tetrahydrodipicolinate + L-glutamate + H2O + H+.

succinyldiaminopimelate transaminase activity

Catalysis of the reaction: 2-oxoglutarate + N-succinyl-LL-2,6-diaminopimelate = L-2-succinylamino-6-oxopimelate + L-glutamate.
