應用
β -淀粉酶可用于水解 α-连接的多糖(例如淀粉和糖原)α连接键。 β Sigma的-淀粉酶可用于各种植物研究,如杨树的碳饥饿研究。β来源于甘薯的-淀粉酶可用于检查该酶对金黄色葡萄球菌生物膜的抑制和去除作用。该酶也可用于由糯玉米淀粉制备β-极限糊精。
β甘薯-淀粉酶可用于:
- 水解淀粉和淀粉-果胶复合物
- 比较金黄色葡萄球菌SH1000生物膜抑制和还原试验中不同来源的淀粉酶
- 样品中的硒形态分析
生化/生理作用
β-淀粉酶可水解由三个或多个α-(1,4)连接D-葡萄糖单元组成的多糖的α-(1,4)葡聚糖键。天然底物(如淀粉和糖原)可被分解成葡萄糖和麦芽糖。β甘薯-淀粉酶是具有相同亚基的四聚体,其222个分子对称排列。
β-淀粉酶在检测糖苷酶之间的酶乱交中起重要作用。
單位定義
在 pH 4.8,温度 20 °C 条件下,一个单位可在 3 分钟内从淀粉中释放出 1.0 mg 麦芽糖。
外觀
溶于2.3 M(NH4)2SO4的结晶混悬液
