产品介绍
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 。 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%。 β -N-acetylglucosaminidase is a lysosomal enzyme used to hydrolyze N-acetyl-β-D-glucosaminides and N-acetyl-β-Dgalactosaminides. It is used in chemoenzymatic synthesis of oligosaccharides based on their effective transglycosylation of β-GlcNAc and β-GalNAcc. It may be a useful tool to study Alzheimer′s Disease . Acetylglucosaminidase from Canavalia ensiformis has been used to study enzymic detachment of biofilms .
生化机理
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。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。
