光系统II，水氧化酶，通过使大气充满氧气来改变进化过程。在这里，我们重建的起源和进化的水氧化在一个前所未有的详细程度，通过研究所有的D1亚基，主要蛋白质协调的水氧化簇（Mn 4CaO 5）的光系统II。我们发现，D1存在于几种形式，使定义明确的分支，其中一些可能已经演变水氧化的起源之前，并提出了许多非典型的特点。最古老的形式是在Gloealphylkilaueensis JS-1的基因组中发现的，它的C-末端与D2的序列同一性高于与任何其他D1的序列同一性。另外两组早期进化的D1对应于那些在长时间的远红外照明和黑暗中表达的。这些非典型的D1形式的特点是一个显着不同的Mn 4CaO 5结合位点和光系统II含有这样的网站可以组装一个非常规的金属簇。第一个D1形式与一套完整的配体Mn 4CaO 5集群与D1蛋白质仅在低氧浓度下表达分组，最新的进化形式是在所有蓝藻和质体中发现的D1的主导类型。此外，我们表明，质体祖先有一个D1更类似于那些在早期分支聚球藻。我们认为，这些形式的D1起源于过渡形式在不同阶段的创新和优化水氧化之前的最后一个共同祖先的所有已知的蓝藻。
Photosystem II, the water oxidizing enzyme, altered the course of evolution by filling the atmosphere with oxygen. Here, we reconstruct the origin and evolution of water oxidation at an unprecedented level of detail by studying the phylogeny of all D1 subunits, the main protein coordinating the water oxidizing cluster (Mn4CaO5) of Photosystem II. We show that D1 exists in several forms making well-defined clades, some of which could have evolved before the origin of water oxidation and presenting many atypical characteristics. The most ancient form is found in the genome of Gloeobacter kilaueensis JS-1 and this has a C-terminus with a higher sequence identity to D2 than to any other D1. Two other groups of early evolving D1 correspond to those expressed under prolonged far-red illumination and in darkness. These atypical D1 forms are characterized by a dramatically different Mn4CaO5 binding site and a Photosystem II containing such a site may assemble an unconventional metal cluster. The first D1 forms with a full set of ligands to the Mn4CaO5 cluster are grouped with D1 proteins expressed only under low oxygen concentrations and the latest evolving form is the dominant type of D1 found in all cyanobacteria and plastids. In addition, we show that the plastid ancestor had a D1 more similar to those in early branching Synechococcus. We suggest each one of these forms of D1 originated from transitional forms at different stages toward the innovation and optimization of water oxidation before the last common ancestor of all known cyanobacteria.
