FUNCTION | Catalyzes the NAD-dependent conversion of D-erythrose 4- phosphate to 4-phosphoerythronate. |
CATALYTIC ACTIVITY | Reaction=D-erythrose 4-phosphate + H2O + NAD(+) = 4-phospho-D- erythronate + 2 H(+) + NADH; Xref=Rhea:RHEA:12056, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:16897, ChEBI:CHEBI:57540, ChEBI:CHEBI:57945, ChEBI:CHEBI:58766; EC=1.2.1.72; |
PATHWAY | Cofactor biosynthesis; pyridoxine 5'-phosphate biosynthesis; pyridoxine 5'-phosphate from D-erythrose 4-phosphate: step 1/5. |
SUBUNIT | Homotetramer. |
SUBCELLULAR LOCATION | Cytoplasm. |
SIMILARITY | Belongs to the glyceraldehyde-3-phosphate dehydrogenase family. Epd subfamily. |
