Fig. 6.
UV-Visible spectrum showing the activity of Eis_Ava (blue), Eis_Msm (red), and Eis_Mtb (green) against KAN (circles) and 6′-glycinyl-KAN (triangles). All Eis homologues are almost inactive against 6′-glycinyl-KAN (as a result the red triangles are completely hidden behind the blue triangles).
