Q-band ENDOR reveals out of plane hydrogen bonds stabilize an anionic ubisemiquinone in cytochrome bo(3) from Escherichia coli

The respiratory cytochrome bo(3) ubiquinol oxidase from E. coli has a high affinity ubiquinone binding site that stabilizes the one-electron reduced ubisemiquinone (SQ(H)), which is a transient intermediate during the electron mediated reduction of O(2) to water. It is known that SQ(H) is stabilized...
