(A) Biosynthesis of UDP-GlcNAc from fructose-6-phosphate proceeds via a GlcNAc-1-phosphate intermediate in the cytoplasm (note: GlmU is bifunctional). Subsequent incorporation of UDP-GlcNAc into PG is shown in Figure 5. (B) GlcNAc-1-P analogues as potential chemical reporters for the PG glycan core.
