Correlations between the Electronic Properties of Shewanella oneidensis Cytochrome c Nitrite Reductase (ccNiR) and Its Structure: Effects of Heme Oxidation State and Active Site Ligation.

Abstract

The electrochemical properties of Shewanella oneidensis cytochrome c nitrite reductase (ccNiR), a homodimer that contains five hemes per protomer, were investigated by UV-visible and electron paramagnetic resonance (EPR) spectropotentiometries. Global analysis of the UV-vis spectropotentiometric results yielded highly reproducible values for the heme… (More)
