Glutathione S-transferase activity was identified in cytosol from human lymphoid-cell lines and peripheral leucocytes (polymorphonuclear-leucocyte/monocyte and small-lymphocyte fractions) and compared with human liver enzyme. The findings of closely similar elution volume in gel filtration, substrate (1-chloro-2,4-dinitrobenzene) and inhibitory (probenecid) kinetics indicate that the liver, leucocyte and lymphoid-cell transferases are closely related. The interaction of reduced glutathione and 1-chloro-2,4-dinitrobenzene was shown to occur in intact-lymphoid-cell culture, to be linear with time and quantity of cells and to have kinetics similar to those of the enzyme reaction catalysed by cytosol.
在人淋巴细胞系的胞质溶胶以及外周白细胞(多形核白细胞/单核细胞和小淋巴细胞组分)中鉴定出谷胱甘肽S-转移酶活性,并与人体肝脏酶进行比较。凝胶过滤中洗脱体积极为相似、底物(1-氯-2,4-二硝基苯)和抑制(丙磺舒)动力学的研究结果表明,肝脏、白细胞和淋巴细胞转移酶密切相关。还原型谷胱甘肽与1-氯-2,4-二硝基苯的相互作用在完整淋巴细胞培养中发生,与细胞的时间和数量呈线性关系,并且其动力学与胞质溶胶催化的酶反应相似。
