ABSTRACT
Genome homology and the presence of a putative biosynthetic gene cluster identified Streptomyces aureorectus DSM 41692 and Streptomyces virens 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'-O-ß-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 Streptomyces calvus, the original source of nucleocidin 1. The identity of 4'-fluoroadenosine 9 was confirmed by a total synthesis as well as by its in vitro enzymatic conversion to metabolite 2 using the glucosyl transferase enzyme, NucGT.
