Abstract

Recently, a fascinating, well-executed, molecular study regarding the direct influence of mitochondrial reactive oxygen species (ROS) formation by the electron transport chain (ETC) on mitochondrial morphology in baker's yeast appeared in PNAS. The findings highlight some very interesting connections between the choice of metabolic substrates, points of entry into the ETC, ROS formation, efficiency of ATP generation, and mitochondrial structures. These reflect both ancient eukaryotic constraints and later specific adaptations of Saccharomyces cerevisiae. However, by not addressing these adaptations, the important wider implications of the article's findings run the risk of being overlooked. There are illuminating connections to the FADH2/NADH ratio concept and new studies replacing ETC components with yeast counterparts in diverse metazoan cells, which will also be discussed.

代谢底物、进入线粒体电子链的点和ROS生成的复杂相互作用:Singh等人对“代谢驱动氧化还原状态对线粒体网络形态的主动控制”的批判性分析,以及用酵母替代物代替ETC成分的研究。
最近,《美国国家科学院院刊》上发表了一篇关于电子传递链(ETC)形成线粒体活性氧(ROS)对面包师酵母线粒体形态直接影响的引人入胜的、执行良好的分子研究。这些发现强调了代谢底物的选择、进入ETC的点、ROS的形成、ATP生成的效率和线粒体结构之间的一些非常有趣的联系。这些都反映了古代真核生物的限制和后来酿酒酵母的特定适应。然而,由于不解决这些适应问题,这篇文章的发现的重要的更广泛的含义有被忽视的风险。这与FADH2/NADH比值概念和在各种后生动物细胞中用酵母对应物代替ETC成分的新研究有启发性的联系,这也将被讨论。

期刊介绍: molecular – cellular – biomedical – physiology – translational research – systems - hypotheses encouraged BioEssays is a peer-reviewed, review-and-discussion journal. Our aims are to publish novel insights, forward-looking reviews and commentaries in contemporary biology with a molecular, genetic, cellular, or physiological dimension, and serve as a discussion forum for new ideas in these areas. An additional goal is to encourage transdisciplinarity and integrative biology in the context of organismal studies, systems approaches, through to ecosystems, where appropriate.
