一般說明

β-半乳糖苷酶存在于细菌、真菌、酵母和动物器官中。也存在于苹果、杏仁和杏等水果中。β-半乳糖苷酶是四聚体,由四条多肽链组成,这四条多肽链由氨基酸组装形成五个结构域。这些区域为果冻卷饼桶型,中心区域作为活性位点,其余区域由 β-夹心结构和纤连蛋白组成。

應用

β(1→4)-半乳糖苷酶,是 肺炎链球菌 的位置特异性酶,可用于:
  • 作为位置特异性酶,在小鼠中研究其末端半乳糖基化作用以及对糖鞘脂(GSPL)的保护作用。
  • 用于消化放射性低聚糖。
  • 作为位置特异性酶,研究其对无毒 杜氏利什曼原虫 克隆(A-LD)毒力特性的影响。

生化/生理作用

β-半乳糖苷酶可水解低聚糖、聚合物和次级代谢产物中的 D-半乳糖基部分。广泛用于乳制品行业,用于去除牛奶和乳制品中的乳糖,使乳糖不耐受的个体获益。β-半乳糖苷酶也可用于食品行业,改善甜度、口感和溶解情况。

單位定義

在pH 5.0、37 °C下,一个单位每分钟可水解1 μmole的对硝基苯基β-D-吡喃半乳糖苷。

外觀

溶于20 mM Tris-HCl,pH 7.5、25 mM NaCl的溶液中
