| dTDP-4-dehydro-6-deoxy-alpha-D-glucopyranose | Aneurinibacillus thermoaerophilus | i.e. dTDP-6-deoxy-D-xylo-hexopyranos-4-ulose. The glycan chain of the S-layer protein of Aneurinibacillus thermoaerophilus L420-91T (DSM 10154) consists of D-rhamnose and 3-acetamido-3,6-dideoxy-D-galactose (D-Fucp3NAc). Thymidine diphosphate-activated (D-Fucp3NAc) serves as precursor for the assembly of structural polysaccharides in Gram-positive and Gram-negative organisms. The biosynthesis of dTDP-3-acetamido-3,6-dideoxy-alpha-D-galactose (dTDP-D-Fucp3NAc) involves five enzymes. FdtA is involved in this pathway | dTDP-3-dehydro-6-deoxy-alpha-D-galactopyranose | i.e. dTDP-6-deoxy-D-xylo-hexopyranos-3-ulose | r |  |
