Other name(s): HgD
Systematic name: (S)-2-hydroxymethylglutarate:NAD+ oxidoreductase
Comments: NADP+ cannot replace NAD+. Forms part of the nicotinate-fermentation catabolism pathway in Eubacterium barkeri. Other enzymes involved in this pathway are EC 1.17.1.5 (nicotinate dehydrogenase), EC 1.3.7.1 (6-hydroxynicotinate reductase), EC 3.5.2.18 (enamidase), EC 5.4.99.4 (2-methyleneglutarate mutase), EC 5.3.3.6 (methylitaconate Δ-isomerase), EC 4.2.1.85 (dimethylmaleate hydratase) and EC 4.1.3.32 (2,3-dimethylmalate lyase).
