[Abstract]  NADPH oxidase is a membrane-bound enzyme that generates (O2-) by transferring electrons from NADPH to molecular oxygen O2. O2-is spontaneously dismasted to the more stable form H2O2. Both O2-and H2O2 are forms ofreactive oxygen species (ROS), which are involved in regulation of many cellular activities such as transcription, intracellular signaling, and host defense. The NADPH oxidase - dependent generation of O2- in total membrane fraction of plant tissue has been determined by the reduction of ... [摘要]  NADPH氧化酶是膜结合酶,其通过将电子从NADPH转移到分子氧O 2而产生(O 2 - )。 O 2被自发地分解成更稳定的形式H 2 O 2。 O 2 - 和H 2 O 2都是反应性氧物质(ROS)的形式,其参与许多细胞活性的调节,例如 转录,细胞内信号传导和宿主防御。 植物组织的总膜部分中NADPH氧化酶依赖性O 2 2-的产生已经通过四唑鎓盐XTT被O 2-还原而确定。 在O 2-的存在下,XTT产生可溶性黄色甲,其可以通过分光光度法定量。
