Popis:	Bacterial ferritin of Azotobacter vinelandii (AvBF) contains a function in accepting electrons from platinum electrode directly for complete iron release in the absence of a mediator. The reduction potentials of electron tunnels of −125, −310, and −370 mV for iron release are determined by direct spectroelectrochemical technique, which suggests which should be defined as midpoint potentials of electron–tunnel–heme on the surface of protein shell. A kinetic study for complete iron release by the electrode reduction at −600 mV fits the zero-order reaction law.
