Abstract
Fatty acids (FAs) participate in extensive physiological activities such as energy metabolism, transcriptional control, and cell signaling. In bacteria, FAs are degraded and utilized through various metabolic pathways, including β-oxidation. Over the past ten years, significant progress has been made in studying FA oxidation in bacteria, particularly in E. coli, where the processes and roles of FA β-oxidation have been comprehensively elucidated. Here, we provide an update on the new research achievements in FAs β-oxidation in bacteria. Using Xanthomonas as an example, we introduce the oxidation process and regulation mechanism of the DSF-family quorum sensing signal. Based on current findings, we propose the specific enzymes required for β-oxidation of several specific FAs. Finally, we discuss the future outlook on scientific issues that remain to be addressed. This paper supplies theoretical guidance for further study of the FA β-oxidation pathway with particular emphasis on its connection to the pathogenicity mechanisms of bacteria.
