Structural Coupling of a Tyrosine Side Chain with the Non-Heme Iron Center in Photosystem II As Revealed by Light-Induced Fourier Transform Infrared Difference Spectroscopy

The non-heme iron is located between the quinone electron acceptors, QA and QB, in photosystem II (PSII), and together with its bicarbonate ligand, it regulates the electron and proton transfer reactions of quinone acceptors. In this study, we have investigated the structural coupling of a nearby Ty...
