Electron-paramagnetic-resonance studies on the redox properties of the molybdenum-iron protein of nitrogenase between +50 and -450 mV.

Abstract

The midpoint potentials, Em, for the oxidation of the characteristic e.p.r. signal with g values near 4.3, 3.7 and 2.01, of the nitrogenase Mo-Fe proteins from a number of bacteria were measured. They were 0mV for Clostridium pasteurianum, -42mV for Azotobacter chroococcum and Azotobacter vinelandii, -95mV for Bacillus polymyxa and -180mV for Klebsiella… (More)
