一般描述

研究领域：神经科学


GABase是一种市售酶混合物，由来自于荧光假单胞菌（Pseudomonas fluorescens）的γ-氨基丁酸氨基转移酶（GABGT）和琥珀酸半醛脱氢酶（SSDH）组成。

应用

来自荧光假单胞菌（Pseudomonas fluorescens）的GABase已被用于GABase测定，以测量GABA（γ-氨基丁酸）的细胞外和细胞内浓度。

生化/生理作用

GABase 催化中枢神经系统中的γ-氨基丁酸（GABA）转化为琥珀酸。它用于测定各种生物学样品中的GABA水平。对羟基苯甲醛（HBA）是潜在的GABase抑制剂。

单位定义

一个酶活性单位是指在pH 8.6、25°C下，每分钟将1.0 μmole的γ-氨基丁酸（GABA）转化为琥珀酸半醛、再转化为琥珀酸，并且化学计量还原1.0 μmole的NADP+所需的酶量。

Many studies have focussed on modulating the activity of γ-aminobutyric acid transaminase (GABA-T), a GABA-catabolizing enzyme, for treating neurological diseases, such as epilepsy and drug addiction. Nevertheless, human GABA-T synthesis and purification have not been established. Thus, biochemical and drug
