| Comments |
This enzyme catalyses a step in a bacterial pathway for the biosynthesis of pyridoxal 5′-phosphate. The enzyme contains a tightly-bound NAD(H) cofactor that is not re-oxidized by free NAD+. In order to re-oxidize the cofactor and restore enzyme activity, the enzyme catalyses the reduction of a 2-oxo acid (such as 2-oxoglutarate, oxaloacetate, or pyruvate) to the respective (R)-hydroxy acid [6]. cf. EC 1.1.1.399, 2-oxoglutarate reductase. |
