Abstract

Photosystem II is the water-oxidizing and O2-evolving enzyme of photosynthesis. How and when this remarkable enzyme arose are fundamental questions in the history of life that have remained difficult to answer. Here, recent advances in our understanding of the origin and evolution of photosystem II are reviewed and discussed in detail. The evolution of photosystem II indicates that water oxidation originated early in the history of life, long before the diversification of cyanobacteria and other major groups of prokaryotes, challenging and transforming current paradigms on the evolution of photosynthesis. We show that photosystem II has remained virtually unchanged for billions of years, and yet the nonstop duplication process of the D1 subunit of photosystem II, which controls photochemistry and catalysis, has enabled the enzyme to become adaptable to variable environmental conditions and even to innovate enzymatic functions beyond water oxidation. We suggest that this evolvability can be harnessed to develop novel light-powered enzymes with the capacity to carry out complex multistep oxidative transformations for sustainable biocatalysis.

光系统的进化与可进化性2。
光系统II是光合作用的水氧化和o2进化酶。这种非凡的酶是如何以及何时产生的,这是生命史上难以回答的基本问题。在这里,我们对光系统II的起源和演化的最新进展进行了详细的回顾和讨论。光系统II的进化表明,水氧化起源于生命历史的早期,远早于蓝藻和其他主要原核生物群体的多样化,挑战和改变了光合作用进化的当前范式。我们表明,光系统II在数十亿年的时间里几乎保持不变,然而光系统II的D1亚基的不间断复制过程控制着光化学和催化作用,使酶能够适应可变的环境条件,甚至创新了水氧化以外的酶功能。我们建议利用这种可进化性来开发新型光能酶,这些酶具有进行复杂的多步氧化转化的能力,以实现可持续的生物催化。
