磷酸甘油酸激酶(PGK)是一种糖酵解酶,可从多种生物体中分离获得。这种典型的铰链弯曲单体酶在三域生物中都很保守。这种酶由单体折叠多肽链构成,可分成两个几乎相同的结构域,每个结构域由两个螺旋链(螺旋链7和14)连接并由一个深裂隙分离。这种排列使该酶具有独特的双叶结构。

應用
来自面包酵母的′3-磷酸甘油酸磷酸激酶(酿酒酵母)已用于:
- 研究低分子量GTP结合蛋白和甘油醛-3-磷酸脱氢酶的抑制机制
- 偶联法测定纯化兔骨骼肌腺嘌呤二核苷酸(NAD+)-依赖性甘油醛-3-磷酸脱氢酶(GAPDH)的反向活性
- 测定甘油醛-3-磷酸脱氢酶
生化/生理作用
3-磷酸甘油酸磷酸激酶催化磷酸基团从1,3-二磷酸甘油酸到ADP的可逆转移,以生成ATP和3-磷酸甘油酸。 3-磷酸甘油酸磷酸激酶的活性对糖酵解和糖异生作用是必需的。磷酸甘油酸激酶(PGK)通过催化两个产生ATP反应之一的糖酵解途径中发挥着重要的作用。它将1,3-二磷酸甘油酸(1,3BPGA)转化为3-磷酸甘油酸(3PGA)。此外,它还通过催化对峙反应生成1,3BPGA和二磷酸腺苷(ADP)参与糖异生过程。由于其参与除能量代谢之外的许多过程,如发病机制、与核酸的相互作用、肿瘤发生和发展、细胞死亡及病毒复制等,PGK还被称为兼职蛋白质。
單位定義
一个单元将在pH6.9,25℃下每分钟将1.0μmol的1,3-二磷酸甘油酸转化为3-磷酸甘油酸。
外觀
3.0 M (NH4)2SO4和 0.04 M 焦磷酸四钠溶液 (pH 8.0) 中的晶体混悬液
分析報告

The presence of low molecular weight GTP-binding proteins was investigated in subcellular fractions from skeletal muscle. Skeletal muscle homogenate, transverse tubules, triads, sarcoplasmic reticulum membranes, and cytosol fractions were separated in sodium dodecyl sulfate-gel electrophoresis and blotted onto nitrocellulose.

Surface-exposed proteins of pathogenic bacteria are considered as potential virulence factors through their direct contribution to host-pathogen interactions. Four families of surface proteins decorate the cell surface of the human pathogen Streptococcus pneumoniae. Besides lipoproteins and LPXTG proteins, also present

S-nitrosothiols are nitric oxide (NO)-derived molecules found in biological systems. They have been variously discussed as both NO reservoirs and as major actors in NO-dependent, but cGMP-independent, signal transduction. Although S-nitrosation of specific cysteine residues has been suggested to represent

Based on the exquisite sensitivity, reproducibility and wide dynamic range of quantitative reverse-transcription real-time polymerase chain reaction (qRT-PCR), it is currently the gold standard for gene expression studies. Target gene expression is calculated relative to a stably expressed reference gene.

Acinetobacter baumannii is a common multidrug-resistant clinical pathogen that is often found in hospitals. The A. baumannii phosphoglycerate kinase (AbPGK) is involved in the key energy-producing pathway of glycolysis and presents a potential target for antibiotic development. AbPGK has been

Glucose metabolism is regulated by the opposing actions of insulin and glucagon. Insulin is released from pancreatic ß cells in response to high blood glucose levels and regulates glucose metabolism through its actions on muscle, liver, and adipose tissue.
