Deoxyxylulose 5-phosphate (DXP) analogs were synthesized and evaluated as alternative substrates and inhibitors of recombinant Synechocystis PCC6803 DXP reductoisomerase (DXR; EC 1.1.1.267). Five of the compounds tested (1,2-dideoxy-D-threo-3-hexulose 6-phosphate, 1-deoxy-l-ribulose 5-phosphate, 2S,3R-dihydroxybutyramide 4-phosphate, 4S-hydroxypentan-2-one 5-phosphate, and 3S-hydroxypentan-2-one 5-phosphate)
合成了5-磷酸脱氧木酮糖(DXP)类似物,并评估了重组拟南芥PCC6803 DXP还原异构酶(DXR; EC 1.1.1.267)的替代底物和抑制剂。测试的化合物中的五种(1,2-二脱氧-D-苏--3-己糖6-磷酸酯,1-脱氧-1-核糖5-磷酸酯,2S,3R-二羟基丁酰胺4-磷酸酯,4S-羟基戊烷-2-酮与磷霉素相比,5-磷酸和3S-羟基戊-2--2-酮(5-磷酸)起相对较弱的竞争性抑制剂的作用。第六种化合物3R,4S-二羟基-5-氧己基膦酸用作替代底物,最近有报道称该化合物与大肠杆菌DXR相同。
