Coenzyme F<sub>420</sub> is a specialized redox cofactor with a negative redox potential. It supports biochemical processes like methanogenesis, degradation of xenobiotics, and the biosynthesis of antibiotics. Although well-studied in methanogenic archaea and actinobacteria, not much is known about F<sub>420</sub> in Gram-negative bacteria. Genome sequencing revealed F<sub>420</sub> biosynthetic genes in the Gram-negative, endofungal bacterium <i>Paraburkholderia rhizoxinica</i>, a symbiont of phytopathogenic fungi. Fluorescence microscopy, high-resolution LC-MS, and structure elucidation by NMR demonstrated that the encoded pathway is active and yields unexpected derivatives of F<sub>420</sub> (3PG-F<sub>420</sub>). Further analyses of a biogas-producing microbial community showed that these derivatives are more widespread in nature. Genetic and biochemical studies of their biosynthesis established that a specificity switch in the guanylyltransferase CofC reprogrammed the pathway to start from 3-phospho-d-glycerate, suggesting a rerouting event during the evolution of F<sub>420</sub> biosynthesis. Furthermore, the cofactor activity of 3PG-F<sub>420</sub> was validated, thus opening up perspectives for its use in biocatalysis. The 3PG-F<sub>420</sub> biosynthetic gene cluster is fully functional in <i>Escherichia coli</i>, enabling convenient production of the cofactor by fermentation. << Less

Cofactor F<sub>420</sub> plays critical roles in primary and secondary metabolism in a range of bacteria and archaea as a low-potential hydride transfer agent. It mediates a variety of important redox transformations involved in bacterial persistence, antibiotic biosynthesis, pro-drug activation and methanogenesis. However, the biosynthetic pathway for F<sub>420</sub> has not been fully elucidated: neither the enzyme that generates the putative intermediate 2-phospho-L-lactate, nor the function of the FMN-binding C-terminal domain of the γ-glutamyl ligase (FbiB) in bacteria are known. Here we present the structure of the guanylyltransferase FbiD and show that, along with its archaeal homolog CofC, it accepts phosphoenolpyruvate, rather than 2-phospho-L-lactate, as the substrate, leading to the formation of the previously uncharacterized intermediate dehydro-F<sub>420</sub>-0. The C-terminal domain of FbiB then utilizes FMNH<sub>2</sub> to reduce dehydro-F<sub>420</sub>-0, which produces mature F<sub>420</sub> species when combined with the γ-glutamyl ligase activity of the N-terminal domain. These new insights have allowed the heterologous production of F<sub>420</sub> from a recombinant F<sub>420</sub> biosynthetic pathway in Escherichia coli. << Less
