Mouse CD73 / NT5E Protein, His Tag (active enzyme)
分子别名(Synonym)
CD73,NT5E,5'-Nucleotidase,5'-NT,NT5,NTE
表达区间及表达系统(Source)
Mouse CD73, His Tag (CD3-M52H9) is expressed from human 293 cells (HEK293). It contains AA Trp 29 - Ser 551 (Accession # Q61503-1).
Predicted N-terminus: Trp 29
蛋白结构(Molecular Characterization)

This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 59.9 kDa. The protein migrates as 66 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
内毒素(Endotoxin)
Less than 1.0 EU per μg by the LAL method.
纯度(Purity)
>90% as determined by SDS-PAGE.
制剂(Formulation)
Lyophilized from 0.22 μm filtered solution in 20 mM Tris, 120 mM NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.

背景(Background)
5'-核苷酸酶(5'-NT),也称为胞外-5'-核苷酸酶或CD73(分化簇73),是由NT5E基因编码的酶。CD73通常用于将AMP转化为腺苷。外切5-三核苷酸酶(5-核糖核苷酸磷酸水解酶)在中性pH下催化嘌呤5-三核苷酸转化为核苷,优选的底物是AMP。其他形式的5-三聚核苷酸酶存在于细胞质和溶酶体中,可以通过其底物亲和力、对二价镁离子的需求、ATP的激活和无机磷酸盐的抑制与胞外NPT5区分开来。罕见的等位基因变异与成人发病的关节和动脉钙化综合征(CALJA)有关,该综合征影响髂、股和胫动脉,减少腿部和手脚关节的循环,导致疼痛。
