一般說明
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。
應用
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。
生化／生理作用
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。
單位定義
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。
外觀
冻干粉末，含有缓冲液和蔗糖作为稳定剂。
