peroxynitrite | addition of ONOO- to cytochrome bd in turnover with ascorbate and N,N,N',N'-tetramethyl-p-phenylenediamine causes the irreversible inhibition of about 15% of the enzyme fraction, due to the NO radical generated from ONOO-. Addition of ONOO- to cells expressing cytochrome bd as the only terminal oxidase, causes about 5% irreversible inhibition of O2 consumption. Purified cytochrome bd in turnover with O2 is able to metabolize ONOO- with an apparent turnover rate as high as about 10 mol ONOO- per mol of enzyme and per s at 25°C | Escherichia coli |
