Effect of exogenous NO on the redox state of purified CcO. Normalized changes in the redox state of cytochromes aa3 from the steady state (Y = 1) to anoxia (Y = 0) against [O2] for 100 nM of purified CcO in turnover (solid black line) and the effect of exogenous NO administered as 50 μM (solid gray line) and 200 μM (dotted black line) DETA-NO.
