General description
微生物淀粉酶是胞外酶，可用于多种工业应用，如面包和麦芽糖浆生产、酱油和豆面酱发酵等。从米曲霉中分离的α-淀粉酶的分子量为51kDa（沉降和扩散）和49kDa（凝胶过滤）。
Application
α-淀粉酶已被用作
- 琼脂平板和羧甲基纤维素清除试验的对照酶，用于筛选淀粉水解的纤维素酶活性，
- 以便探讨小麦淀粉在冷冻面团中
- 抑制金黄色葡萄球菌生物膜的作用。
Biochem/physiol Actions
米曲霉α-淀粉酶(Ao α-淀粉酶)酶催化可溶性淀粉和相关底物中α-1,4糖苷键的水解。这些底物被分解并释放较短的低聚糖和α-极限糊精。
Other Notes
1个酶活力单位（U）相当于在pH6.0和25℃下每分钟释放1μmol麦芽糖所需的酶量（淀粉符合Zulkowsky，货号85642，作为底物）。
用于测定食物中的脂肪；应用于糖苷键的（选择性）水解/缩合。
