一般描述
神经氨酸酶是一种促进流感病毒从感染细胞释放并促进病毒传播的水解酶。
量热法研究表明，神经氨酸酶中心催化结构域侧翼的两个凝集素样结构域可作为含唾液酸底物的识别和结合位点。
应用
来自霍乱弧菌的神经氨酸酶已被用于一项描述五步纯化方法的研究中。 它还被用于一项探究白血病L1210肿瘤细胞修饰的研究中。
神经氨酸酶被用作糖缀合物分布和底物特异性研究的细胞表面探针。
质量
不含防腐剂。
单位定义
除特殊规定，在37 °C pH 5.0条件下，一个单位可在每分钟内从NAN-乳糖或牛颌下粘蛋白中释放将1.0 μ摩尔的N-乙酰神经氨酸。价格是基于使用NAN-乳糖作为底物的单位。
外形
含有0.15 M 氯化钠及及4 mM 叠氮化钠并经0.2 μm滤器过滤的pH 5.5 50 M 醋酸钠中的溶液。
制备说明
通过亲和色谱度我们的III类进行进一步纯化。

Vibrio cholerae neuraminidase (VCNA) plays a significant role in the pathogenesis of cholera by removing sialic acid from higher order gangliosides to unmask GM1, the receptor for cholera toxin. We previously showed that the structure of VCNA is composed of

Polyomaviruses are small, non-enveloped DNA tumor viruses that cause serious disease in immunosuppressed people, including progressive multifocal leukoencephalopathy (PML) in patients infected with JC polyomavirus, but the molecular events mediating polyomavirus entry are poorly understood. Through genetic knockdown approaches, we

A selective and potent inhibitor of neuraminidases, a hydrolase that is responsible for processing sialylated glycoconjugates, is a promising drug candidate for various infective diseases. The current study demonstrates that the use of an aglycone-focused library of 2-difluoromethylphenyl α-sialosides is
