Respiratory enzyme activities of T11-10, T11-10/2, and T22-11 transformants.

<p>Respiratory activities were measured on membrane fractions of T11-10, T11-10/2 and T22-11 mutants. NADH:Duroquinone corresponds to the rotenone-sensitive NADH:duroquinone oxidoreductase activity (nmol of NADH oxidized min⁻¹ mg of proteins⁻¹); NADH:Ferricyanide corresponds to the NADH:Fe(CN)₆³⁻ oxidoreductase activity (nmol of K3Fe(CN)₆³⁻ reduced min⁻¹ mg of proteins⁻¹); CII+III corresponds to the succinate:cytochrome <i>c</i> oxidoreductase activity (nmol cytochrome <i>c</i> reduced min⁻¹ mg of proteins⁻¹); CIV corresponds to the cytochrome <i>c</i> oxidase activity (nmol of cytochrome <i>c</i> oxidized min⁻¹ mg of proteins⁻¹). Asterisks indicate statistically significantly differences using Student <i>t</i> test with a significance threshold of 0.05. <a href="http://www.plosgenetics.org/article/info:doi/10.1371/journal.pgen.1002946#s2" target="_blank">Results</a> are means of 3 to 6 independent experiments.
