一般描述
来源于米尔伊丽莎白菌的糖苷内切酶F1是一种聚糖特异性酶。
应用
切割天冬酰胺连接或游离的低聚甘露糖、以及杂化但不是复合的低聚糖。
来源于米尔伊丽莎白菌的糖苷内切酶F1已被用于解除人血色素沉着蛋白 (HFE) 与阳离子非依赖性甘露糖-6-磷酸受体 (CI-MPR) 的结合并用于岩藻糖基化 N-糖肽的糖基化。
生化/生理作用
来源于米尔伊丽莎白菌的糖苷内切酶F1在蛋白质聚糖结构中壳二糖核心的两个N-乙酰葡糖胺残基的裂解中起到重要作用。它介导高甘露糖和杂交寡聚糖的裂解。

Fungal β-N-acetylhexosaminidases are inducible extracellular enzymes with many biotechnological applications. The enzyme from Penicillium oxalicum has unique enzymatic properties despite its close evolutionary relationship with other fungal hexosaminidases. It has high GalNAcase activity, tolerates substrates with the modified N-acyl group
