Bacterial quinones are lipophilic redox compounds involved in important cellular roles such as electron transport in respiratory and photosynthetic chains. However, a growing body of research has now revealed that quinones have additional functions in bacterial physiology, with significant consequences for colonization and persistence in different ecological niches. The aim of this review is to provide an updated view of the functions of bacterial quinones, with particular emphasis on their importance for bacterial metabolism, gene regulation, and stress resistance. We provide evidence that quinones have also a deep impact on the composition and function of bacterial ecosystems.
细菌醌是亲脂性的氧化还原化合物，参与许多重要的细胞作用，如呼吸和光合链中的电子传递。然而，越来越多的研究表明，醌在细菌生理学中具有额外的功能，对其在不同生态位中的定殖和持续存在具有重要意义。本文旨在提供细菌醌功能的最新观点，特别强调其对细菌代谢、基因调控和抗应激的重要性。我们提供的证据表明，醌对细菌生态系统的组成和功能也有深远的影响。
