产品介绍
人α-淀粉酶由包含496个氨基酸的单个多肽链组成，其在1号染色体上进行编码。其在唾液腺或胰腺中产生。唾液和胰腺α-淀粉酶具有同源的一级序列，但表现出不同的切割模式。
α-淀粉酶可水解三个或更多个D-葡萄糖单元通过α-（1,4）连接的多糖中的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。
酶活定义：在pH 6.9、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。
| 外观： | 含有(NH4)2SO4、柠檬酸钠和氯化钠的冻干粉。 |
|---|---|
| 溶解性： | 推荐溶解缓冲液：20 mM磷酸钠与6.7 mM氯化钠，pH 6.9 |
| 储存条件： | -20℃ |
| EC编号： | 3.2.1.1 |
