4-磷酰D-赤糖酸酯

4-Phospho-D-erythronate is an intermediate in the synthesis of pyridoxal 5'-phosphate in some bacteria and an inhibitor of ribose 5-phosphate isomerase. Phosphorylated aldonic acids are strong inhibitors of 6-phosphogluconate dehydrogenase, and 4-phospho-D-erythronate (4PE) and 4-phospho-D-erythronohydroxamate are two of the strongest inhibitors of the Trypanosoma brucei enzyme.
