"Water Molecules Gating a Photoinduced One Electron Two Protons Transfer in a Tyr/His model of Photosystem II"

https://onlinelibrary.wiley.com/doi/abs/10.1002/anie.201804498

Our study provides an unprecedented example of a light‐induced electron‐transfer process in a TyrZ/His190 model of photosystem II, evidencing the movement of both the phenol and imidazole protons along an isoenergetic pathway.

Dear Dr Sircoglou,

Congratulations !

According to the evaluation of referees the results reported in your Communication are “highly important” or even “very important”. Less than 10% of our manuscripts receive such a positive review. We recommend that you tell the publicity/press department of your institute about your publication and the excellent reviews that it has received; a press release could be possible. Furthermore, you are welcome to submit graphical material suitable for display on the outside or inside covers of Angewandte Chemie. Manuscripts that have received such positive recommendations are favored in our selection process. Since there is a close competition for the cover, it is absolutely necessary that the proposal fits our layout.

Investigating the Uptake of Arsenate by Chlamydomonas reinhardtii Cells and its Effect on their Lipid Profile using Single Cell ICP–MS and Easy Ambient Sonic-Spray Ionization–MS

Abstract

The complementary use of single cell atomic mass spectrometry (MS) and ambient molecular MS allowed for the in-depth study of arsenate uptake by Chlamydomonas reinhardtii cells and of the effect this toxic metalloid species has on their lipid profile. Compared to conventional inductively coupled plasma mass spectrometry (ICP–MS) analysis, in which case hundreds of thousands of cells are digested and then analyzed, it is demonstrated that single cell (SC) ICP–MS provides uptake data that are potentially of greater biological relevance. This includes the arsenic mass distribution within the cell population, which fits to a log-normal probability function, the most frequently contained arsenic mass within the cells (1.5–1.8 fg As per cell), and the mean arsenic uptake value (ranging from 2.7 to 4.1 fg As per cell for the three arsenate incubation concentrations, that is, 15, 22.5, and 30 μg As per mL) derived from the log-normal arsenic mass distribution within the cell population. The SC approach also allows for differentiating the arsenic present in and/or adsorbed on the cells, from the arsenic present in the extracellular solution, in a single analysis. In a similar fashion, ambient molecular MS in the form of desorption easy ambient sonic spray ionization (EASI) -MS was used to rapidly profile cell membrane lipids from cells spotted directly on a glass slide. EASI–MS analysis revealed that cells grown in the presence of increasing concentrations of arsenate exhibited changes in the degree of saturation of their membrane lipids, as was observed by the increasing intensity ratio of lipids with less unsaturated acyl chains to the same type of lipids with more unsaturated fatty acid chains. Thus, indicating “homeoviscous adaptation” of extraplastidial and thylakoid cell membranes, induced by the presence of arsenate.
