应用
β-N-乙酰氨基葡萄糖苷酶是用于水解 N-乙酰基-β-D-氨基葡萄糖苷和 N-乙酰基-β-D-半乳糖胺的溶酶体酶。基于 β-GlcNAc 和 β-GalNAcc 的有效转糖基作用，它用于寡糖的化学酶促合成。其可能是研究阿尔茨海默病的有用工具 。来自洋刀豆的乙酰氨基葡萄糖苷酶已被用于研究生物膜的酶解离 。
生化/生理作用
这种酶，有时称为 β-N-乙酰氨基己糖苷酶，据报道可释放末端 β-连接来自多种底物的 N-乙酰葡糖胺和 N-乙酰半乳糖胺。β-N-酰基葡糖胺酶的活性可以用显色底物对硝基苯基-N-乙酰基-β-D-氨基葡萄糖苷测定。 β-N-酰基葡糖胺酶水解末端非还原性 N-乙酰基-D-己糖胺残基。这种酶含有两种主要的同工酶，Hex A（异源二聚体）和 Hex B（同源二聚体）。N-乙酰氨基葡萄糖、乙酰胺、N-2-乙酰胺基-2-脱氧葡萄糖胺、N-乙酰诺吉瑞霉素和 N-乙酰脱氧诺吉瑞霉素是已知的抑制剂。

单位定义
一个单位将在 pH5.0、25 °C下每分钟将 1.0μmole 对硝基苯基 N-乙酰基-β-D-氨基葡萄糖水解成对硝基苯酚和N-乙酰基-D-葡糖胺。
外形
2.5 M 混悬液 (NH4)2SO4，pH 7.0
分析说明
在 pH 4.0 时，对硝基苯基 β-N-乙酰氨基半乳糖在 pH 5.0 时水解速率约为对硝基苯基 β-N-乙酰氨基葡萄糖水解速率的 50%。

A 12 year-old female presented with a seven-year history of progressive muscle weakness, atrophy, tremor and fasciculations. Cognition was normal. Rectal biopsy revealed intracellular storage material and biochemical testing indicated low hexosaminidase activity consistent with juvenile-onset G(M2)-gangliosidosis. Genetic evaluation revealed
