Supplementary Figure 1: Chemical structures of tunicamycin and the natural substrates of GPT and MraY.

Chemical structure of the competitive inhibitor tunicamycin A1 is shown at the top, while the structures of the natural substrates (UDP-GlcNAc for GPT and UDP-MurNAc-pentapeptide for MraY) are shown at the bottom. All compounds contain uridine moieties and either a GlcNAc or MurNAc moiety.
