"The non-heme iron is located between the quinone electron acceptors, Q(A) and Q(B), 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 Tyr residue with the non-heme iron center using Fourier transform infrared (FTIR) spectroscopy," scientists in Tsukuba, Japan report (see also Spectroscopy).
"Light-induced FC2+/Fe3+ FTIR difference spectra of PSII core complexes from unlabeled and [4-C-13]Tyr-labeled Thermosynechococcus elongatus revealed that the CO stretching (nu CO) bands of a Tyr side chain are ...
