DSM 41692 and DSM 41465 are producers of the antibiotic nucleocidin and 4'-fluoroadenosine is identified as a co-product.

Genome homology and the presence of a putative biosynthetic gene cluster identified DSM 41692 and DSM 41465 as candidate producers of the antibiotic nucleocidin 1. Indeed when these bacterial strains were cultured in a medium supplemented with fluoride (4 mM) they each produced nucleocidin 1 and the previously identified 4'-fluoro-3'--β-glucosylated adenosine 2 and its sulfamylated derivative 3. In both of these cases 4'-fluoroadenosine 9 is also identified as a natural product although it has never been observed during fermentations of , the original source of nucleocidin 1. The identity of 4'-fluoroadenosine 9 was confirmed by a total synthesis as well as by its enzymatic conversion to metabolite 2 using the glucosyl transferase enzyme, NucGT.
