Publication Abstract from PubMed

Tetrahydrodipicolinate N-succinyltransferase is an enzyme present in many bacteria that catalyzes the first step of the succinylase pathway for the synthesis of meso-diaminopimelate and the amino acid L-lysine. Inhibition of the synthesis of meso-diaminopimelate, a component of peptidoglycan present in the cell wall of bacteria, is a potential route for the development of novel anti-bacterial agents. Here, we report the crystal structure of the DapD tetrahydrodipicolinate N-succinyltransferase from Escherichia coli at 2.0 A resolution. Comparison of the structure with the homologous enzyme from Mycobacterium bovis reveals the C-terminal helix undergoes a large rearrangement upon substrate binding, which contributes to cooperativity in substrate binding.
