additional information | Ureibacillus thermosphaericus | meso-diaminopimelate dehydrogenase catalyzes the NAD(P)-dependent oxidative deamination of meso-diaminopimelate stereoselectively acting on the D-configuration of meso-diaminopimelate. The enzyme is highly selective for meso-diaminopimelate as the electron donor, and NADP+ but not NAD+ can serve as the electron acceptor | ? | - |
