Absence of electron transfer-associated changes in the time-dependent X-ray free-electron laser structures of the photosynthetic reaction center

The paper investigates time-dependent structural changes in the photosynthetic reaction center using XFEL data and finds no clear link between structural changes and electron transfer events.

Characterization of Tryptophan Oxidation Affecting D1 Degradation by FtsH in the Photosystem II Quality Control of Chloroplasts

This study shows that Trp oxidation at the N-terminus of D1 protein enhances FtsH-mediated degradation during high-light stress in PSII repair.

Proton-mediated gating mechanism of anion channelrhodopsin-1

The paper investigates the proton-mediated gating mechanism of GtACR1 by analyzing mutants and using computational methods to determine the protonation states and their effects on absorption wavelengths.

Basicity of N5 in semiquinone enhances the rate of respiratory electron outflow in Shewanella oneidensis MR-1

This study shows that the basicity of N5 in semiquinone cofactors enhances the rate of extracellular electron transport in Shewanella oneidensis MR-1 by facilitating protonation-dependent electron outflow.
