The structure of Thermotoga maritima TM1643 has been found to contain an N-terminal Rossmann fold domain (which binds the NAD(P)+ cofactor) and a C-terminal alpha/beta domain [1]. Enzymatic characterisation of TM1643 revealed that it possesses NAD or NADP-dependent dehydrogenase activity toward L-aspartate but no aspartate oxidase activity [1]. Members of this group share some structural similarity to several other NAD(P)+-dependent oxidoreductases, including inositol 1-phosphate synthase, dihydrodipicolinate reductase, and ASA-DH [1]. It has been proposed that in Thermotoga maritima, TM1643 catalyses the first reaction of de novo biosynthesis of NAD from aspartate, and it produces iminoaspartate required for this pathway.

PF03447Homoserine dehydrogenase, NAD binding domain (NAD_binding_3)Homoserine dehydrogenase, NAD binding domainThis domain adopts a Rossmann NAD binding fold. The C-terminal domain of homoserine dehydrogenase contributes a single helix to this structural domain, which is not included in the Pfam model.Domain
