Figure 6. Inhibition of phenotype rescue by ecHinT inhibitor.

A) The structure of tryptamine 5′-guanosine monophosphate (TpGd). B) The structure of tryptamine guanosine carbamate (TpGc). C) TpGc exhibits a non-competitive inhibition profile. D) Wild-type E. coli BW25113 was grown in M9 medium supplemented with either 20 mM glucose or 20 mM alanine in the presence (brown bar) or absence (blue bar) of 100 µM TpGC. OD₆₀₀ values were determined after 48 h.
