應用

β-葡萄糖苷酶还可用于合成葡萄糖苷和岩藻糖苷(在制药、化妆品和洗涤剂行业具有多种潜在的应用)、从类黄酮和异黄酮糖苷中水解除去糖苷配基部分、增强果汁和葡萄酒的风味、以及寡糖的生物合成。

生化/生理作用

β-葡萄糖苷酶可参与β-D-糖苷中连接碳水化合物残基的β-糖苷键的水解。它们可将内切和外切葡聚糖酶产生的纤维二糖和纤维寡糖转化为葡萄糖。

單位定義

1 U 对应于在 pH 5.0 和 37°C 下,每分钟释放1 μmol 葡萄糖的酶量(水杨苷作为底物)

其他說明

β-葡萄糖苷酶在纤维素水解中的作用:评论;通过同时糖化和发酵,用于燃料乙醇生产的纤维素的酶水解;碳水化合物与氨基酸衍生物的立体特异性附着;酶催化合成有机介质中的烷基 β-D-葡糖苷

The transglycosylation from raffinose and lactose to Aloc-Ser-OMe is catalyzed respectively by alpha and beta galactosidases. Transglycosylation from cellobiose has been achieved with beta-glucosidase. The simplicity of the enzymatic synthesis, the stereospecificity of the condensations in one-pot reactions and the
