Nucleocidin is an adenosine derivative containing 4’-fluoro and 5’-O-sulfamoyl substituents. In this study, nucleocidin biosynthesis is examined in two newly discovered producers, Streptomyces virens B-24331 and Streptomyces aureorectus B-24301, which produce nucleocidin and related derivatives at titres 30-fold greater than S. calvus. This enabled the identification of two new O-acetylated nucleocidin derivatives, and a potential glycosyl-O-acetyltransferase. Disruption of nucJ, nucG, and nucI, within S. virens B-24331, specifying a radical SAM/Fe-S dependent enzyme, sulfatase, and arylsulfatase, respectively, led to loss of 5’-O-sulfamoyl biosynthesis, but not fluoronucleoside production. Disruption of nucN, nucK, and nucO specifying an amidinotransferase, and two sulfotransferases respectively, led to loss of fluoronucleoside production. Identification of S. virens B-24331 as a genetically tractable and high producing strain sets the stage for understanding nucleocidin biosynthesis and highlights the utility of using 16S-RNA sequences to identify alternative producers of valuable compounds in the absence of genome sequence data.
