本研究基于噁嗪170高氯酸盐(O17)-乙基纤维素(EC)膜和固定于EC及水凝胶聚氨酯(PU)基质中的酶,构建了用于L-精氨酸(L-Arg)和L-天冬酰胺(L-Asn)的比率荧光生物传感器。L-Arg传感膜利用精氨酸酶和脲酶催化L-Arg及尿素水解产生氨;L-Asn传感膜利用天冬酰胺酶催化L-Asn水解产生氨。O17-EC膜与氨反应...

Biochemical characterization and immobilization of Erwinia carotovoral-asparaginase in a microplate for high-throughput biosensing of l-asparagine.

Enzyme and microbial technology 2016 Labrou NE, Muharram MM

L-天冬酰胺酶(L-ASNase,E.C. 3.5.1.1)催化 L-天冬酰胺转化为 L-天冬氨酸和氨。本研究从 Erwinia carotovora 中克隆、表达并表征了一种新的 L-ASNase(EcaL-ASNase),在 Escherichia coli 中以可溶蛋白形式表达,并通过离子交换色谱单步纯化至均一。作者采用动力学...
