The discovery of penta-peptides inhibiting the activity of the formylglycine-generating enzyme and their potential antibacterial effects against Mycobacterium tuberculosis .

The formylglycine-generating enzyme is a key regulator that converts sulfatase into an active form. Despite its key role in many diseases, enzyme activity inhibitors have not yet been reported. In this study, we investigated penta-peptide ligands for FGE activity inhibition and discovered two hit peptides. In addition, the lead peptides also showed potential antibacterial effects in a Mycobacterium tuberculosis model.
