α-葡萄糖苷酶(α-glucosidase，EC 3.2.1.20)又被称为α-葡萄糖苷水解酶或葡萄糖基转移酶(GTase)，是一种α-D-葡萄糖苷酶。它可以从低聚糖类底物的非还原末端切开α-1,4糖苷键释放出葡萄糖，或将游离出的葡萄糖残基转移到另一糖类底物形成仅α-1,6糖苷键，从而得到非发酵性的低聚糖。α-葡萄糖苷酶来源广泛，在人体糖原的降解和动植物、微生物的糖类代谢方面具有重要的生理功能。
酶活定义
每小时产生1μg葡萄糖所需的酶量定义为一个α-葡萄糖转苷酶活力单位。
酶活检测方法：参见QB 2525-2001。
产品特性
最适作用温度：50℃，合适的作用温度：50-55℃
最适作用pH：5.0，合适的作用pH：4.8-5.4
使用说明
抑制剂
铜、钛、钴等金属离子对本品有一定的影响。铅、铝、锌等金属离子对本品有较强的抑制作用。
贮存
1.建议密封储藏于干燥、低温的环境中（≤25℃），最好在冷藏条件下（4-8℃）储藏。
2.25℃以下，液体可以储存3个月，保质期内酶活不会降低于产品标示的活力；4℃以下，可较长时间储存。
3.本品只用于科研领域研究，不可食用或者用于食品生产。
