Studies on the structure, function and mechanisms of the cbb3 type cytochrome c oxidase from Vibrio cholerae and the cytochrome bo3 ubiquinol oxidase from Escherichia coli
… that Y288 is required for PM formation and Y173 is crucial for F formation. CW-EPR experiments demonstrated WT and Y288H generated a radical of the same origin while Y173 gave rise to a different radical species and Y288H+Y173F failed to generate radical of any kind. Auxotrophic strains were …

Biochemical characterization of a-type heme-copper oxidases in escherichia coli, bacillus subtilis and thermus thermophilus
… a stable tyrosyl radical assigned on Y173 was observed in reaction with oxygen in YII184F bo3 mutant using EPR spectroscopy. This is the first time that a tyrosyl radical has been shown generated by O2. Moreover, we proposed a proton coupled electron transfer mechanism (PCET) causes …
