应用
使用β-半乳糖苷酶生产用于酒精分析的稳定的单一试剂。
生化/生理作用
β-半乳糖苷酶可将乳糖切割成单糖成分、葡萄糖和半乳糖。它还在反馈环中催化葡萄糖转糖基化为β-半乳糖苷酶的诱导物异乳糖。
单位定义
一个单元将在37°C pH 7.3 下每分钟水解 1.0βmol o -硝基苯基 β- D -半乳糖苷，转化为 o -硝基酚和 D -半乳糖。

A series of lipidated guanidino and urea derivatives of 1,5-dideoxy-1,5-imino-d-xylitol were prepared from d-xylose using a concise synthetic protocol. Inhibition assays with a panel of glycosidases revealed that the guanidino analogues display potent inhibition against human recombinant β-glucocerebrosidase with IC50

Aging can be viewed as a quasi-programmed phenomenon driven by the overactivation of the nutrient-sensing mTOR gerogene. mTOR-driven aging can be triggered or accelerated by a decline or loss of responsiveness to activation of the energy-sensing protein AMPK, a critical
