Pantothenate synthetase catalyses the ATP-dependent condensation of D-pantoate and β-alanine to form pantothenate. Ten analogues of the reaction intermediate pantoyl adenylate, in which the phosphodiester is replaced by either an ester or sulfamoyl group, were designed as potential inhibitors of the enzyme. The esters were all modest competitive inhibitors, the sulfamoyls were more potent, consistent with their closer structural similarity to the pantoyl adenylate intermediate.
泛酸盐合成酶催化
ATP依赖的D-
泛解酸和
β-丙氨酸缩合形成
泛酸盐的过程。设计了十种反应中间物泛酰
腺苷酸的类似物作为酶的潜在
抑制剂,其中
磷酸二酯被酯或
磺胺甲基所取代。这些
酯类都是较弱的竞争性
抑制剂,而
磺胺甲基类则更具活性,与其更接近于泛酰
腺苷酸中间体的结构相似性相符。
