脱氮副球菌氧化磷酸化：在通往线粒体的过程中的保留、增益、损失和教训

线粒体的氧化磷酸化装置与在α-变形菌的细胞质膜中发现的装置之间有许多相似之处，例如Paracocus plasticans。这些相似之处在这里审查一起考虑线粒体和细菌对应物之间的差异，以及从现代线粒体的许多细菌呼吸蛋白的损失。c型细胞色素的组装在进化上特别重要，因为在α-变形菌中使用的翻译后装置在植物中发现，例如在真核生物物种中，包括各种藻类和雅各布虫，但在后生动物和锥虫的线粒体中被不同的系统取代。所有线粒体细胞色素都具有被后生动物系统识别的N末端序列特征，而细菌对应物则没有，这表明细菌系统从真核生物中的丢失发生在真核细胞色素中已经存在的识别序列的背景下。有趣的是，在cytochromesc 1的情况下，后生动物的推定识别功能似乎基本上存在于细菌蛋白中。从P.具有经典呼吸控制的线粒体膜囊泡是一个有价值的系统，可以从中吸取关于什么控制线粒体呼吸和ATP合成速率这一长期争论的话题的经验教训。© 2018 IUBMB Life，70（12）：1214-1221，2018
There are many similarities between the oxidative phosphorylation apparatus of mitochondria and those found in the cytoplasmic membranes of alpha‐proteobacteria, exemplified byParacocus denitrificans. These similarities are reviewed here alongside consideration of the differences between mitochondrial and bacterial counterparts, as well as the loss from the modern mitochondria of many of the bacterial respiratory proteins. The assembly ofc‐type cytochromes is of particular evolutionary interest as the post‐translational apparatus used in the alpha‐proteobacteria is found in plants, and for example in eukyarotic species including algae of various kinds together with jakobids, but has been superseded by different systems in mitochondria of metazoans and trypanosomatids. All mitochondrial cytochromeschave the N‐terminal sequence feature that is recognised by the metazoan system whereas the bacterial counterparts do not, suggesting that the loss of the bacterial system from eukaryotes occurred in the context of an already present recognition sequence in the eukaryotic cytochromes. Interestingly, in the case of cytochromesc1the putative recognition features for the metazoans appear to be substantially present in the bacterial proteins. The ability to prepare fromP. denitrificansinverted membrane vesicles with classic respiratory control presents a valuable system from which to draw lessons concerning the long debated topic of what controls the rates of respiration and ATP synthesis in mitochondria. © 2018 IUBMB Life, 70(12):1214–1221, 2018
