生化/生理作用

从糖蛋白上释放未取代的Ser-和Thr-连接β-Gal-(1→3)-α-GalNAc(核心1型O-聚糖)。 用唾液酸、乳糖胺(半乳糖-N-乙酰氨基葡萄糖)或岩藻糖取代的二糖核心将阻止水解并防止寡糖从蛋白质中释放出来。在使用O-糖苷酶切割之前,可能需要使用糖酵解酶进行预处理以从O-聚糖中去除取代糖。

包装

提供5×反应缓冲液,250mM NaH2PO4,pH 5.0。

单位定义

在37 °C、pH 6.5下,一单位在每分钟内可水解1 μmole的硝基苯基半乳糖N-生物苷(β-Gal-(1→3)-α-GalNAc-1→ΟC6H4NO2)。

外形

溶于50 mM磷酸钾,pH 7.5

The structures that contribute to shunt resistance (Rs) in esophageal epithelium are incompletely understood, with 35-40% of Rs known to be calcium-dependent, reflecting the role of e-cadherin. Two calcium-independent candidates for the remaining approximately 60% of Rs have been identified:
