Mitochondrial Oxidative Phosphorylation (OXPHOS) provides ATP for driving cellular functions. In plants, OXPHOS takes place in the context of photosynthesis. Indeed, metabolism of mitochondria and chloroplasts is tightly linked. OXPHOS has several extra functions in plants. This review takes a view on the OXPHOS system of plants, the electron transfer chain (ETC), the ATP synthase complex and the numerous supplementary enzymes involved. Electron transport pathways are especially branched in plants. Furthermore, the "classical" OXPHOS complexes include extra subunits, some of which introduce side activities into these complexes. Consequently, and to a remarkable degree, OXPHOS is a multi-functional system in plants that needs to be efficiently regulated with respect to all its physiological tasks in the mitochondria, the chloroplasts, and beyond. Regulatory mechanisms based on posttranslational protein modifications and formation of supramolecular protein assemblies are summarized and discussed.

植物线粒体的氧化磷酸化系统

线粒体氧化磷酸化 (OXPHOS) 为驱动细胞功能提供 ATP。在植物中，OXPHOS 发生在光合作用的背景下。事实上，线粒体和叶绿体的代谢是紧密相连的。OXPHOS 在植物中有几个额外的功能。这篇综述对植物的 OXPHOS 系统、电子转移链 (ETC)、ATP 合酶复合物和众多相关的辅助酶进行了研究。电子传输途径在植物中特别分支。此外，“经典”OXPHOS 复合物包括额外的亚基，其中一些将副活性引入这些复合物中。因此，在显着程度上，OXPHOS 是植物中的一个多功能系统，需要对其在线粒体、叶绿体、超越。总结和讨论了基于翻译后蛋白质修饰和超分子蛋白质组装形成的调控机制。
