CC Rule:MF_01825}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=4-phospho-D-erythronate + NAD(+) = (R)-3-hydroxy-2-oxo-4-
CC phosphooxybutanoate + H(+) + NADH; Xref=Rhea:RHEA:18829,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:57540, ChEBI:CHEBI:57945,
CC ChEBI:CHEBI:58538, ChEBI:CHEBI:58766; EC=1.1.1.290;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_01825};
CC -!- PATHWAY: Cofactor biosynthesis; pyridoxine 5'-phosphate biosynthesis;
CC pyridoxine 5'-phosphate from D-erythrose 4-phosphate: step 2/5.
CC {ECO:0000256|HAMAP-Rule:MF_01825}.
CC -!- SUBUNIT: Homodimer. {ECO:0000256|HAMAP-Rule:MF_01825}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_01825}.
CC -!- SIMILARITY: Belongs to the D-isomer specific 2-hydroxyacid
CC dehydrogenase family. PdxB subfamily. {ECO:0000256|HAMAP-
CC Rule:MF_01825}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_01825}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
