Dihydrodipicolinate reductase (DapB) reduces the alpha,beta-unsaturated cyclic imine, dihydro-dipicolinate. This reaction is the second committed step in the biosynthesis of L-lysine and its precursor meso-diaminopimelate, which are critical for both protein and cell wall biosynthesis. The C-terminal domain of DapB has been proposed to be the substrate- binding domain.	Domain
