一般描述
硝基还原酶是一种黄素蛋白，由NfsB基因编码。它包含一个二聚体，每个亚基具有217个氨基酸和活性位点。该结构具有FMN和与酶结合的底物。
应用
大肠杆菌来源硝基还原酶可结合猪肝酯酶(PLE)用于偶联结合反应。它还还可结合探针HyCL-3和HyCL-4-AM针对大鼠肝微粒体进行化学发光响应研究。
生化/生理作用
硝基还原酶(NTR)可催化还原硝基芳香族底物和醌。NTR的F124K突变体可用于癌症治疗，改善药物CB1954的敏化作用。
硝基还原酶在NADPH或NADH为还原剂的氧还系统中有重要作用。
硝基还原酶增强了生命体对于含氮药物，比如甲硝唑的敏感度，它将氮基团转化为有毒的氮自由基。
能够还原奎宁。 该酶可以激活抗体引导酶前药治疗的前药。
物理属性
含有PBS的冻干粉。 作为辅药不含有BSA
单位定义
在pH7.4、37℃、存在甲萘醌和NADH的条件下，一单位酶每分钟能够还原1μmole细胞色素C。
制备说明
使用没有动物组分的材料生产。

A fundamental obstacle in gene therapy for cancer treatment is the specific delivery of an anticancer gene product to a solid tumor. Although several strategies exist to control gene expression once a vector is directly introduced into a tumor, as
