Application
γ-Glu-Cys可用于研究谷胱甘肽合成酶的活性位点和动力学。它也被用于从拟南芥 组织中提取和量化低分子量硫醇。
Biochem/physiol Actions
γ-L-谷氨酰基-L-半胱氨酸（γ-Glu-Cys）是用于通过谷胱甘肽合成酶生物合成L-谷胱甘肽的底物。γ-Glu-Cys通过裂解谷胱甘肽的Cys-Gly肽键而产生。它对植物螯合素的形成也是必需的，植物螯合素是富含半胱氨酸的硫醇反应性肽。

Lys18, Arg86, Asn283, Ser286, Thr288 and Glu292 of glutathione synthetase from Escherichia coli B are presumed to be highly concerned with the substrate, gamma-L-glutamyl-L-cysteine (gamma-Glu-Cys), binding by X-ray crystallography and affinity labeling studies. Using site-directed mutagenesis, we investigated functional roles
