Escherichia coli uses fatty acids as a sole carbon and energy source during aerobic growth by means of the enzymes encoded by the fad regulon. We report that this bacterium can also grow on fatty acids under anaerobic conditions provided that a terminal respiratory electron acceptor such as nitrate is available. This anaerobic utilization pathway is distinct from the well-studied aerobic pathway in that (i). it proceeds normally in mutant strains lacking various enzymes of the aerobic pathway; (ii). it functions with fatty acids (octanoate and decanoate) that cannot be used by wild-type E. coli strains under aerobic conditions; and (iii). super-repressor mutants of the fadR regulatory locus that block aerobic growth on fatty acids fail to block the anaerobic pathway. We have identified homologues of the FadA, FadB and FadD proteins required for aerobic fatty acid utilization called YfcY, YfcX and YdiD, respectively, which are involved in anaerobic growth on fatty acids. A strong FadR binding site was detected upstream of the yfcY gene consistent with microarray analyses, indicating that yfcYX expression is negatively regulated by FadR under aerobic growth conditions. In contrast, transcriptional regulation of ydiD appears to be independent of FadR, and anaerobic growth on fatty acids is not under FadR control. These three genes are conserved in the available genome sequences of pathogenic E. coli, Shigella and Salmonella strains. << Less
