Name  Dihydrodipicolinate reductase, N-terminal Short Name  DapB_N
Type  Domain Description  Dihydrodipicolinate reductase catalyzes the second step in the biosynthesis of diaminopimelic acid and lysine, the NAD or NADP-dependent reduction of 2,3-dihydrodipicolinate into 2,3,4,5-tetrahydrodipicolinate [, , ].In Escherichia coliand Mycobacterium tuberculosis, dihydrodipicolinate reductase has equal specificity for NADH and NADPH, however in Thermotoga maritimathere it has a greater affinity for NADPH []. In addition, the enzyme is inhibited by high concentrations of its substrate, which consequently acts as a feedback control on the lysine biosynthesis pathway. In T. maritima, the enzyme also lacks N-terminal and C-terminal loops which are present in enzyme of the former two organisms.This entry represents the N-terminal domain of dihydrodipicolinate reductase which binds the dinucleotide NAD(P)H.
