Abstract
Retraction of ‘The reductive phase of Rhodobacter sphaeroides cytochrome c oxidase disentangled by CO ligation’ by Hendrik Mohrmann et al., Phys. Chem. Chem. Phys., 2017, DOI: 10.1039/c7cp06480b.
We, the named authors, hereby wholly retract this Physical Chemistry Chemical Physics article. After publication, we found a mistake in the data analysis, which originated from an honest error made during preparation of the article. In particular, the number of transferred electrons n is reciprocal, i.e. 0.85 for the first and 0.33 for the second transition. Furthermore, the mid-point potential of heme a in CO-bound cytochrome c oxidase has been derived from the change in intensity of a vibrational band of the IR spectrum whose assignment is ambiguous. Thus, our conclusions relating to electron-coupled proton transfer involving the heme cofactors are flawed.
The authors would like to apologize for any inconvenience to readers.
