Background-corrected protein film SW voltammograms of (A–C) α3Y, (D–F) α3(2,3)F2Y, (G) α3(3,5)F2Y, (H) α3(2,3,5)F3Y, and (I) α3(2,3,6)F3Y. The proteins were adsorbed onto the surface of a PGE electrode and voltammograms recorded in 20 mM APB, 40 mM KCl, pH 5.54 ± 0.06 buffer at 25 °C. SWV settings: Equilibration time 5 s, step potential 0.15 mV, SW pulse amplitude 25 mV, SW frequency 440 Hz.
