家蝇金属硫蛋白的研究进展

Research advances in metallothionein in Musca domestica

金属硫蛋白(MT)是一类广泛存在于生物体内的金属结合蛋白,富含半胱氨酸的小分子蛋白,能螯合多种金属离子,因其功能独特,近年来对MT各方面的研究日益受到重视。该文简述了家蝇MT的结构特点、理化性质和分布情况,以及参与体内解毒、清除自由基和微量元素代谢功能的研究现状及进展。

Metallothioneins （MT） are a class of cysteine-rich, low-molecular-weight metal-binding proteins widely distributed in organisms, which can chelate various metal ions. In recent years, MT has been increasingly studied in different aspects due to its special functions. This paper briefly describes the structural characteristics, physical and chemical properties, and distribution ofMT and reviews the research advances in its participation in detoxication, free radical scavenging, and trace element metabolism.
