一般說明
研究领域:神经科学
醇脱氢酶的同源二聚体结构在C端具有辅酶结合结构域,在N末端具有催化结构域。活动部位位于域间裂隙。NAD+在活性位点的结合会引起构象变化,从而形成醇底物的结合位点。

應用
醇脱氢酶(ADH)被用于逆转精神分裂症断裂基因1(DISC1-FL)和DB7细胞裂解物中缺乏的3-[4,5-二甲基噻唑-2-基]-2,5二苯基四唑溴化物(MTT)测定的减少。
生化/生理作用
醇脱氢酶催化醇氧化转化为醛。醇脱氢酶(ADH)催化的乙醇代谢引发活性氧(ROS)和一氧化氮(NO)的产生,导致线粒体和细胞蛋白氧化损伤,并进一步与神经炎症和神经系统疾病的发生有关。
單位定義
一个单位对应于在pH 7.0和30℃(NADPH作为辅助因子)下,每分钟减少1 μmol丙酮所需的酶量

Kava (Piper methysticum) is an ethnomedicinal shrub native to the Polynesian islands with well-established anxiolytic and analgesic properties. Its main psychoactive principles, kavalactones, form a unique class of polyketides that interact with the human central nervous system through mechanisms distinct
