d-ribofuranose ring and an l-amino acid moiety. The conversion of l-to d-amino acid configuration is catalyzed by the PLP-dependent epimerase AbmD. The d- ribo to d- xylo conversion of the thiofuranose ring appears according to gene deletion experiments to be mediated by AbmJ, which is annotated as a radical S-adenosyl-l-methionine (SAM) enzyme. These studies establish several key steps in the assembly of the
