Conformational Changes and H-Bond Rearrangements during Quinone Release in Photosystem II

[Image: see text] In photosystem II (PSII) and photosynthetic reaction centers from purple bacteria (PbRC), the electron released from the electronically excited chlorophyll is transferred to the terminal electron acceptor quinone, Q(B). Q(B) accepts two electrons and two protons before leaving the...
