摘要:

氢化酶作为一种可催化氢气氧化与质子还原的金属酶,在生物体的氢代谢过程中发挥着关键作用。已有研究表明,氢气干预可对植物的生长发育和抗逆性产生积极影响,同时一些高等植物的内源性产氢现象也已得到证实,然而关于催化内源性产氢的氢化酶目前了解较少。虽然已有多项研究表明,叶绿体可能是高等植物产氢的关键部位,但是鉴于多种植物在种子萌发时仍然可以产氢,而种子萌发过程中叶绿体还没有生成,加上氢化酶在进化上与线粒体复合物Ⅰ具有同源性,在对氢化酶研究现状进行概述的基础上,提出了高等植物线粒体具有氢化酶活性的猜想,并总结了线粒体存在氢化酶活性的初步实验证据,以期为后续线粒体与氢化酶的关系研究提供参考依据。

Abstract:

As a metalloenzyme that can catalyze hydrogen oxidation and proton reduction, hydrogenase plays a key role in the hydrogen metabolism of organisms. Previous studies have shown that hydrogen intervention has a positive impact on plant growth and stress resistance. At the same time, the phenomenon of endogenous hydrogen production in some higher plants has also been confirmed. However, little is known about the hydrogenase that catalyzes endogenous hydrogen production. Although many studies have shown that chloroplasts may be the key part of hydrogen production in higher plants, in view of the fact that many plants can still produce hydrogen during seed germination when chloroplasts have not been formed, combining that hydrogenase has evolutionary homology with mitochondrial complex Ⅰ, the hypothesis that higher plant mitochondria have hydrogenase activity was put forward and the preliminary experimental evidence of hydrogenase activity in mitochondria was summarized on the basis of summarizing the research status of hydrogenase, hoping to provide a reference for the follow-up study on the relationship between mitochondria and hydrogenase.

Key words: hydrogenase, higher plant, mitochondrion, complex Ⅰ
