Application

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。

Biochem/physiol Actions

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。

General description

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。

Other Notes

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。

Glutamate (GLU) and gamma-aminobutyric acid (GABA) are neurotransmitters (NTs) with an essential role in signal transmission in the brain. Brain disorders, such as epilepsy, Alzheimer's and Parkinson's diseases, and traumatic brain injury can be linked to imbalances in the GLU-GABA

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
