一般描述

葡萄糖-6-磷酸脱氢酶(G-6-PDH)由His-Asp催化二联体构成,并以同二聚体形式存在。结构上,G-6-PDH在辅酶结合结构域内包含罗斯曼折叠构成的二核苷酸结合区域。还具有一个较大的β + α结构域,在374位有一个独特的天冬氨酸残基。

应用

来自肠膜明串珠菌的葡萄糖-6-磷酸脱氢酶已联用己糖激酶进行小鼠肝样品中的葡萄糖测定。

生化/生理作用

葡萄糖-6-磷酸脱氢酶(G-6-PDH)可使用烟酰胺腺嘌呤二核苷酸磷酸(NADP+)或NAD+作为辅酶,在细菌代谢中具有重要作用。
葡萄糖-6-磷酸脱氢酶(G6PD)催化葡萄糖-6-磷酸转化为6-磷酸葡糖酸内酯,作为磷酸戊糖途径的第一步。

单位定义

一个单元在NAD 存在下,在pH 7.8,30℃ 下,每分钟将 1.0 μmole的D-葡萄糖-6-磷酸氧化成 6-磷酸-D-葡萄糖酸盐。

外形
