How the first metabolic network was organized to power a cell remains an enigma. Now, simple iron–sulfur peptides have been used to generate a pH-gradient across a protocell membrane by catalysing hydrogen peroxide reduction. This indicates that short peptides could have fulfilled the role of redox active metalloproteins in early life.

第一个代谢网络如何为细胞提供动力仍然是一个谜。现在，简单的铁硫肽已被用于通过催化过氧化氢的还原而在原生细胞膜上产生pH梯度。这表明，短肽在生命早期可能已经发挥了氧化还原活性金属蛋白的作用。
