DIRECT ELECTROCHEMISTRY IN THE CHARACTERIZATION OF REDOX PROTEINS - NOVEL PROPERTIES OF AZOTOBACTER 7FE FERREDOXIN

DIRECT ELECTROCHEMISTRY IN THE CHARACTERIZATION OF REDOX PROTEINS - NOVEL PROPERTIES OF AZOTOBACTER 7FE FERREDOXIN

Fast diffusion-dominated electron transfer between Azotobacter chroococcum 7Fe ferredoxin, FdI, and pyrolytic graphite 'edge' electrodes, promoted by aminoglycosides, permits detailed voltammetric studies and preparation of oxidation states inaccessible by chemical titration. The [3Fe-4S]...
