(S)-2,3,4,5-tetrahydrodipicolinate + H2O + succinyl-CoA = (S)-2-succinylamino-6-oxoheptanedioate + CoA Inhibited by p-(chloromercuri)benzenesulfonic acid and cobalt. Amino-acid biosynthesis; L-lysine biosynthesis via DAP pathway; LL-2,6-diaminopimelate from (S)-tetrahydrodipicolinate (succinylase route): step 1/3. Homotrimer. Belongs to the transferase hexapeptide repeat family. Was originally thought to originate from Mycobacterium bovis (PubMed:8880935, PubMed:9012664, PubMed:9671504 and PubMed:11910040). However, there is now convincing evidence that this is incorrect (PubMed:19394346). The source is unknown, but the sequence similarity suggests the protein is of enterobacterial origin.
