應用

肠系膜明串珠菌来源葡萄糖 6-磷酸脱氢酶已用于:

  • PGI 的偶联分光光度测定法(F6P-G6P 反应)
  • 使用烟草叶研究淀粉时程
  • 测定北美黑橡(Quercus velutina Lam. saplings)根和茎样品中的葡萄糖含量
  • 使用野生型和转基因拟南芥整株幼苗的淀粉样本测定葡萄糖

生化/生理作用

6-磷酸葡萄糖脱氢酶 (G6PD) 在所有组织中均有表达,并产生还原形式的烟酰胺腺嘌呤二核苷酸磷酸 (NADPH),有助于细胞避免氧化压力。G6PD不足是一种 X 连锁的遗传性基因缺陷,由G6PD基因常见突变引起。
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。

單位定義

在 NAD 存在下,在pH 7.8,30°C 下,1 个单位将每分钟氧化 1.0 μmol D-6-磷酸葡萄糖至 6-磷酸-D-葡萄糖酸盐。

外觀

含有Ficoll和Tris 缓冲盐的冻干粉

Phosphoglucoisomerase (PGI) isomerizes fructose 6-phosphate (F6P) and glucose 6-phosphate (G6P) in starch and sucrose biosynthesis. Both plastidic and cytosolic isoforms are found in plant leaves. Using recombinant enzymes and isolated chloroplasts, we have characterized the plastidic and cytosolic isoforms of

Cancer cells have long been recognized to exhibit unique bioenergetic requirements. The apoptolidin family of glycomacrolides are distinguished by their selective cytotoxicity towards oncogene-transformed cells, yet their molecular mechanism remains uncertain. We used photoaffinity analogs of the apoptolidins to identify
