General description
该酶是糖酵解途径的一部分。同时，其在通过葡萄糖进行果糖-1,6-二磷酸（FDP）的工业生产中也很重要。其分子质量为约189kDa，并且由四个亚基组成，每个亚基的分子量为约50kDa。 最适pH为9-10，等电点为4.2。
Application
来自Sigma的酶已被用于测定根瘤菌突变株中的果糖6-磷酸。
磷酸葡萄糖异构酶（PGI）是一种对D-葡萄糖6-磷酸酯和D-果糖-6-磷酸酯相互转化至关重要的酶。PGI负责糖酵解的第二步，并参与葡萄糖生成。它在细菌和真核生物中高度保守。它可用于糖含量测定中将果糖转化为葡萄糖。该产品来源于 嗜热脂肪芽孢杆菌。
Biochem/physiol Actions
磷酸葡萄糖异构酶是一种异构酶、神经白细胞介素、自分泌运动因子以及分化和成熟的中介体。
Physical form
含Tris缓冲液的冻干粉
Other Notes
一个酶活性单位是指在pH 9.0、温度30 °C条件下，每分钟将1.0 μm的D-果糖-6-磷酸转化为D-葡萄糖-6-磷酸所需的酶量。
