抗坏血酸氧化酶 来源于南瓜 属
lyophilized powder, 1,000-3,000 units/mg protein
别名:
L-抗坏血酸：氧氧化还原酶, 抗坏血酸酶
Application
西葫芦来源抗坏血酸氧化酶可用于：
- 作为在培养基中分化成成骨细胞的补充剂
- 在单脱氢抗坏血酸还原酶分析中氧化抗坏血酸产生单脱氢抗坏血酸
- 测定抗坏血酸(AsA)和脱氢抗坏血酸(DHA)浓度
来自南瓜（ Cucurbita sp.）的抗坏血酸氧化酶可用于研究氧化应激和热应激反应以及耐受性。 Sigma的抗坏血酸氧化酶已被用于抗坏血酸测定，以研究拟南芥（ Arabidopsis ） 的热应激反应。
Biochem/physiol Actions
抗坏血酸氧化酶(AO)可通过调节质外体的还原/氧化（氧化还原）参与细胞生长。这种酶能在质外体中合成氧化分子脱氢抗坏血酸(DHA)。此外，还参与了细胞延长和增大发育。
抗坏血酸氧化酶可将抗坏血酸转化为脱氢抗坏血酸。 它对L-抗坏血酸和一些类似物具有高度特异性。 抗坏血酸氧化酶是分子量约140kda的二聚体。
General description
抗坏血酸氧化酶是一种同二聚体酶，每个亚基包含552个氨基酸残基（西葫芦）。每个亚基对应的分子量为70 kDa。这种酶主要存在于植物、真菌和真细菌中。
Other Notes
在pH 5.6、温度25℃条件下，每分钟将1.0 μm的 L-抗坏血酸盐氧化成脱氢抗坏血酸盐所需的酶量为一个单位。

In plant cells, antioxidants keep reactive oxygen species at low concentrations, avoiding oxidative damage while allowing them to play crucial functions in signal transduction. However, little is known about the role of antioxidants during fruit maturation, especially in legumes. Snap
