一般描述
α-淀粉酶（α-1,4-葡聚糖-4-葡聚糖水解酶）属于糖基水解酶 13 家族。两个天门冬氨酸残基和一个谷氨酸残基是 α-淀粉酶的主要催化残基。所有淀粉酶都具有三个结构域，即具有中央（β/α）8 桶的结构域 A、结构域 B 以及包含结构域 C 的希腊钥匙模体的 β-结构。
我们致力于为您提供更环保的替代产品，以符合“绿色化学的12项原则”的一项或多项原则要求。该产品针对淀粉水解研究进行了优化，可提高能效并防止浪费。有关详细信息，请参阅《Biofiles》的文章。
应用
α-淀粉酶（芽孢杆菌来源）可用于：
- 作为一种分散酶检测金黄色葡萄球菌生物膜的降解
- 木薯淀粉的酶法水解
- 植物性原生非晶颗粒淀粉的酶解
生化/生理作用
α-淀粉酶介导淀粉、麦芽寡糖和糖原在α-D-(1,4)-糖苷键上的水解。芽孢杆菌是α-淀粉酶异构生产的重要细胞工厂。此外，还有从枯草芽孢杆菌菌株中提取到细胞外分泌的耐热淀粉酶的报道。
单位定义
一个单位是在pH 6.9和25°C下每分钟释放 1 μmol 麦芽糖的酶量（采用产品货号 85642 作为底物）
其他说明
细菌 α 的热稳定性-淀粉酶类 ；对甘薯淀粉、直链淀粉和支链淀粉的作用方式 ；对天然小麦淀粉的作用。
