General description
尿苷-5′-二磷酸葡萄糖焦磷酸化酶（UDP-glc-PPase）普遍存在于植物、酵母、细菌和哺乳动物中。这种酶是由八个相同亚基组成的八聚体。
Application
来自面包酵母的尿苷-5′-二磷酸葡萄糖焦磷酸化酶′已用于：
- 合成尿苷-5′-二磷酸葡萄糖(UDP-Glc)-13C9
- 量化水稻中蔗糖合酶（SUS）的活性
- 研究己糖激酶和糖原合成酶控制青蛙卵母细胞通量的作用
Biochem/physiol Actions
尿苷-5′-二磷酸葡萄糖焦磷酸化酶（UDP-glc-PPase）参与催化UDP-葡萄糖的合成。这种酶的活性需要二价阳离子，例如Mg2+、Ca2+、Mn2+、Ni2+。
Physical form
冻干粉，不含硫酸盐，含柠檬酸缓冲盐
Other Notes
一个单位将在25℃和pH 7.6下，每分钟由尿苷-5′-二磷酸葡萄糖和无机焦磷酸盐形成1.0 μmole的1-磷酸葡萄糖。

Bacterial galU coding for a uridine diphosphate-glucose pyrophosphorylase plays an important role in carbohydrates biosynthesis, including synthesis of lipopolysaccharides (LPS), membrane-derived oligosaccharides, and capsular polysaccharides. In this study, we characterized the galU mutant of Pseudomonas syringae pv. syringae 61 (Psy61)
