A protein conformational change associated with the photoreduction of the primary and secondary quinones in the bacterial reaction center.

abstract：:The catalytic cycle of heme peroxidases involves two reactive states, compound I and compound II. Although their reduction potentials at pH 7 are similar, compound I is in general more reactive towards organic substrates than compound II. The different reactivities have until now remained unexplained. In this study, t...
