摘要: 谷氧还蛋白(GRX)是一种小分子热稳定的蛋白质,广泛存在于动物、植物和微生物中。其中在动物和人体内研究较多,在植物中研究相对较少,在不同植物中谷氧还蛋白基因的数量和种类也不尽相同。谷氧还蛋白通常含有一个保守的CXXC/S活性位点,根据其活性位点的氨基酸序列可将其分为3类:CPYC型、CGFS型和CC型。其中,前2种为真核生物所共有,而CC类型为陆生植物所特有,且数量最多。谷氧还蛋白发挥作用时有单巯基和双巯基机制,可以在谷胱甘肽分子的帮助下还原二硫键或蛋白质谷胱甘肽加合物。谷氧还蛋白、谷胱甘肽、NADPH和谷胱甘肽还原酶共同组成了谷氧还蛋白系统。谷氧还蛋白在植物中与硫氧还蛋白系统、抗坏血酸谷胱甘肽循环系统等共同参与细胞的氧化还原状态的维持以及各类细胞进程的调节,并且在植物细胞抵抗生物以及非生物的氧化胁迫中起着十分重要的作用。另外,谷氧还蛋白还在植物生长发育、氮代谢、铁硫簇形成等方面具有重要作用。本研究就植物中谷氧还蛋白的命名、分类、作用机制以及在植物体内发挥的功能进行汇总,以期对其有更深入的了解。

Abstract: Glutaredoxin(GRX)is a small moleculer and heat-stable protein, which is widely found in animals, plants and microorganisms. Among them, there are more studies in animals and humans, and relatively few studies in plants. The number and types of glutaredoxin genes in different plants are not the same. Glutaredoxins usually contain a conservative CXXC/S active site, which can be divided into three types according to the amino acid sequence of the active site:CPYC type, CGFS type and CC type. Among them, the first two types are shared by eukaryotes, while the CC type is unique to terrestrial plants and has the largest number. Glutaredoxin has single sulfhydryl and double sulfhydryl mechanism when it works, and it can reduce disulfide bonds or protein glutathione adducts with the help of glutathione molecules. Glutaredoxin, glutathione, NADPH and glutathione reductase together form the glutathione system. Glutaredoxin in plants, together with the thioredoxin system, the ascorbate glutathione cycle system, and so on. Participate in the maintenance of the redox state of the cell and the regulation of various cell processes, and it resists biological and non-biological oxidation in plant cells. It plays a very important role in coercion. In addition, glutaredoxin also plays an important role in plant growth and development, nitrogen metabolism and iron-sulfur cluster formation. This article briefly introduces the naming, classification, mechanism of action and functions of glutaredoxin in plants in order to have a deeper understanding of it.

Key words: Plants, Glutaredoxin, Mechanism of action, Function, Biological stress
