一般描述

己糖激酶负责催化糖酵解的第一步。它导致葡萄糖和 ATP 形成葡萄糖-6-磷酸和 ADP。 葡萄糖-6-磷酸脱氢酶是磷酸戊糖途径中的关键酶。负责葡萄糖-6-磷酸和 NADP +(烟酰胺腺嘌呤二核苷酸磷酸)转化为 6-磷酸葡萄糖酸内酯和 NADPH。

应用

己糖激酶/6-磷酸葡萄糖脱氢酶已用于测定血浆葡萄糖水平。

组分

EC 2.7.1.1 & 1.1.1.49

单位定义

在+ 25°C和pH 7.6条件下,1个单位(U)HK将在1分钟内磷酸化1μmol的D-葡萄糖。
在+ 25℃和pH 7.6条件下,1单位(U)G6P-DH将在1分钟内氧化1μmol葡萄糖-6-磷酸。
在偶联试验中,每μmolD-葡萄糖磷酸化产生1μmolNADH。

体积活性:以葡萄糖和ATP为底物,+ 25℃时产生340u己糖激酶/ml。170 U葡萄糖-6-磷酸脱氢酶/ ml(+ 25°C,葡萄糖-6-磷酸为底物)

外形

用 3.2 M 硫酸铵溶液(pH 值约为 6)混悬。己糖激酶与 G6P-DH 混合制备。HK:G6P-DH的蛋白质含量约为2:1。

其他说明

仅用于生命科学研究。不用于诊断程序。

The serine/threonine kinase Akt/PKB is a major downstream effector of growth factor-mediated cell survival. Activated Akt, like Bcl-2 and Bcl-xL, prevents closure of a PT pore component, the voltage-dependent anion channel (VDAC); intracellular acidification; mitochondrial hyperpolarization; and the decline in

Type 2 diabetes is a very prevalent chronic disease. Among dietary factors for its prevention and treatment, interest has grown in satiating fibre (konjac glucomannan) and spirulina. Our previous studies suggest that glucomannan itself and/or in conjunction to spirulina displayed

Most cancer cells exhibit increased glycolysis and use this metabolic pathway for generation of ATP as a main source of their energy supply. This phenomenon is known as the Warburg effect and is considered as one of the most fundamental

Glucose-6-phosphate dehydrogenase (G6PD) is the rate-limiting enzyme of the pentose phosphate pathway. Many scientists think that the roles and regulation of G6PD in physiology and pathophysiology have been well established as the enzyme was first identified 80 years ago. And
