Manganese superoxide dismutase (SOD2) is a matrix enzyme expressed in mitochondria. SOD2 is a known free radical scavenger, and has been shown to play a role in several nervous system diseases.

锰超氧化物歧化酶(SOD2)是线粒体基质酶，作为细胞内氧自由基的清除剂，SOD2与氧化应激相关的神经系统疾病密切相关。

The new research shows that production of the vital forms of manganese requires that the fungi and bacteria be actively producing superoxide.

新的研究显示，能否生成这种重要的锰化合物，取决于真菌和细菌是否能够生产超氧化物。

So creating conditions that encourage the organisms to make the superoxide could be the first step in a pathway by which they help manganese to literally do the dirty work.

因此为这种有机体合成超氧化物创造有利条件，只是帮助矿物质锰“干脏活”这个过程中的第一步。
