DE   4-phosphoerythronate dehydrogenase.
AN   4-O-phosphoerythronate dehydrogenase.
AN   4PE dehydrogenase.
AN   erythronate-4-phosphate dehydrogenase.
CA   4-phospho-D-erythronate + NAD(+) = (R)-3-hydroxy-2-oxo-4-
CA   phosphooxybutanoate + H(+) + NADH.
CC   -!- This enzyme catalyzes a step in a bacterial pathway for the
CC       biosynthesis of pyridoxal 5'-phosphate.
CC   -!- The enzyme contains a tightly-bound NAD(H) cofactor that is not
CC       re-oxidized by free NAD(+).
CC   -!- In order to re-oxidize the cofactor and restore enzyme activity,
CC       the enzyme catalyzes the reduction of a 2-oxo acid (such as
CC       2-oxoglutarate, oxaloacetate, or pyruvate) to the respective (R)-
CC       hydroxy acid. cf. EC 1.1.1.399.
