A radical notion: Calculated isotropic 13 C hyperfine coupling constants are distinctly different for the anionic ubisemiquinone model UQ .− (picture, left) rather than the protonated UQH . (picture, right) and can distinguish between the two in electron transfer proteins such as cytochrome bo3, cytochrome bc 1 , or photosynthetic reaction centers.
