Construction of a CO2‐Fixing Compartment Using a Shape‐Transforming DNA Scaffold

Chemistry – A European Journal, EarlyView.
A shape‐transforming DNA scaffold encapsulates RuBisCO within a controllable, self‐contacting compartment that mimics the carboxysome. The scaffold switches between open and closed states, enabling direct comparison of identical enzyme populations in different microenvironments.

Enzymatic Prenylation of Proteins and Peptides: From Cysteine S‐Prenylation to Tryptophan‐Selective Biocatalysis

Chemistry – A European Journal, EarlyView.
This review highlights biocatalytic prenylation as a versatile strategy for tailoring the functional properties of peptides and proteins. By comparing branched isoprenoids with linear lipids, we illustrate how specific prenyl architectures modulate the behaviors of lipidated proteins within membrane environments.

Single GAF Domain Phytochrome Exhibits a pH‐Dependent Shunt on the Millisecond Timescale

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
During their light‐induced photocycle, phytochromes can engage in a thermal reversion back to the initially excited state, denoted as a shunt. This study investigates a pH‐dependent shunt transition in the Pfr state of the All2699g1 phytochrome from Nostoc punctiforme using UV/Vis laser flash photolysis and kinetic modeling. The findings suggest a keto‐

Filtering efficiency and feeding mechanisms of Daphnia pulex on Microcystis aeruginosa and Nannochloropsis [PDF]

, 2012
The filtering and feeding rate of Daphnia pulex from the Old Durham Reservoir, Durham, NH, were measured to determine the feeding efficiency on different concentrations of non-toxic Nannochloropsis (Class Eustigmatophyceae) and toxigenic cyanobacteria ...

Rational Optimization of Self‐Reporting Alcohol‐Oxidizing RhIII$^{\mathrm{III}}$ Complexes

European Journal of Inorganic Chemistry, EarlyView.
A series of four different [(NN)Rh(Cp*)X]n+$^{\mathrm{n+}}$ complexes (NN = chelating α$\alpha$‐diimine ligand, Cp* = pentamethylcyclopentadienyl, X = Cl, solvent) are reported which all do possess a colorimetric self‐reporting property upon alcohol oxidation formation of the Rh(I) state. Analysis of alcohol oxidation rates

Faecal Microbiota Transplantation in Anorexia Nervosa: A Systematic Review of Methodologies, Outcomes, and Challenges With Recommendations for Future Studies

European Eating Disorders Review, EarlyView.
ABSTRACT Objective Anorexia nervosa (AN) is a severe psychiatric disorder displaying an altered gut microbiome. Faecal microbiome transplantation (FMT) has emerged as a powerful research tool and potential treatment option in AN due to the microbiome‐gut‐brain axis. Current studies are limited and reveal variable FMT protocols.

Genomic profiles of four novel cyanobacteria MAGs from Lake Vanda, Antarctica: insights into photosynthesis, cold tolerance, and the circadian clock

Frontiers in Microbiology
Cyanobacteria in polar environments face environmental challenges, including cold temperatures and extreme light seasonality with small diurnal variation, which has implications for polar circadian clocks.
