This is formed in a In ﬁnal form 22 December 2017 protein-bound form which permits the semiquinone to vary its electronic and redox properties. This Available online 24 December 2017 can be achieved by hydrogen bonding acceptance by one or both oxygen atoms or as we now propose by restricted orientations for the methoxy groups of the headgroup. We show how the orientation of Keywords: the two methoxy groups of the quinone headgroup affects the electronic structure
