EPR and solid-state NMR studies on the mechanism of cytochrome bo3 ubiquinol oxidase from escherichia coli
… and D75H mutant cytochrome bo3 samples with selectively isotope labeled Arg, Gln or His were prepared from these C43(DE3) auxotroph strains, and the semiquinone radicals at the QH-site of these samples were analyzed by pulsed EPR spectroscopy. Selective 15N labeling has revealed the Nε of R71 …
