Comment on Photosystem II: light‐dependent oscillation of ligand composition at its active site: existence of O6 in S3‐state photosystem II revealed by omit maps

Acta Crystallographica Section D, Volume 82, Issue 6, Page 574-586, June 2026.
We reanalyzed our XFEL data, the results of which showed the insertion of O6 during the S2–S3 transition in water oxidation by photosystem II. These results contradict the interpretation proposed by Wang that there is no insertion of O6 during the S2–S3 transition.Photosystem II (PSII) catalyzes the light‐driven oxidation of water to molecular oxygen ...

A novel fusion tool to enable G protein‐coupled receptor structure determination

Acta Crystallographica Section D, Volume 82, Issue 6, Page 655-663, June 2026.
The development of a new fusion tool in which a β‐lactamase fusion tag and a binding partner enabled the structure determination of an antagonist‐bound G protein‐coupled receptor by cryo‐EM is reported.Structure determination of G protein‐coupled receptors (GPCRs) plays an important role in accelerating drug development against this medically important

Greenwashing: Motivations, causes and consequences

International Review of Economics & Finance
We discuss motives and outcomes of corporate greenwashing as well as factors that contribute to it. We argue that in the presence of benefits accrued to corporate social responsibility, economic agents with short-term horizons may be incented to engage ...

Does Private Information Always Hurt Retail Investors? The Impact of Private Information on Cost of Equity: Moderating Role of Investment Adjustment

SAGE Open, 2023
Private information puts naïve traders at a significant trading disadvantage and at the same it provide crucial signals managers for investment adjustment. These two forces have opposing effects on the cost of equity, and the overall effect is determined

Photoisomerization detected in a fully wavelength‐tunable rhodopsin mimic system

Acta Crystallographica Section D, Volume 82, Issue 6, Page 664-671, June 2026.
The mechanism of retinal photoswitching is illuminated in a designed rhodopsin mimic. Two mechanisms, a conventional cis–trans isomerization and an unprecedented `photodehydration', are observed at atomic resolution in single crystals.We describe the photoisomerization of the retinylidene protonated Schiff base in human retinol‐binding protein II ...

Cefdinir binding to a class A β‐lactamase revealed by serial cryo‐crystallography

Acta Crystallographica Section D, Volume 82, Issue 6, Page 672-682, June 2026.
Serial cryo‐crystallography reveals the structure of the extended‐spectrum β‐lactamase CTX‐M‐14 in complex with the third‐generation cephalosporin antibiotic cefdinir.One of the most common resistance mechanisms against antibiotics employed by Gram‐negative bacteria involves the production of β‐lactamases, resulting in rapid hydrolysis of the ...

Cryo‐EM structure of ALC1 in an open conformation bound to a PARylated nucleosome

Acta Crystallographica Section D, Volume 82, Issue 6, Page 683-699, June 2026.
Reanalysis of a publicly available cryo‐EM dataset identifies a new conformation of the oncogenic chromatin remodeler ALC1/CHD1L bound to a PARylated nucleosome. This new structure reveals the position of the macro domain in the complex, and may help to understand the large conformational change leading to the activation of ALC1.Nucleosomes are the ...
