A protein that transports amino acids across the cell membrane was found to bind only a few amino acids efficiently. To find the specificity, many different amino acids and substrate analogs were used as competitive inhibitors in transport studies at pH 5.9 with L-histidine (Km = 10 μM). The Ki values calculated from Lineweaver-Burk plots are shown in the table below. Comparing the structures of L-histidine and the competitive inhibitors (for which most of them, you should know their structures!), what can you conclude about the characteristics of molecules that this transport protein binds at its active site?
