The X‐Ray Crystal Structure of BorF, the Flavin Reductase Subunit of a Two‐Component Flavin‐Dependent Tryptophan Halogenase

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT BorF is a short‐chain flavin reductase from a desert soil bacterium that uses NADH to reduce FAD to FADH2, which is used by the tryptophan‐6‐halogenase BorH to chlorinate tryptophan in the biosynthetic pathway of borregomycin A. The X‐ray crystal structure of BorF bound to FAD was solved to 2.37 Å by molecular replacement.

Exploring the Fragmentation of Sodiated Species Involving Covalent‐Bond Cleavages for Metabolite Characterization

open access: yesRapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale Electrospray (ESI), the most popular desorption/ionization technique used in mass spectrometry‐based metabolomics, generates both protonated and deprotonated molecules, as well as adduct ions, sodium being the most frequent monoatomic cation entering their composition.

Potassium‐Doped Borophane Nanosheets: A Multifunctional Platform for Reversible Hydrogen Storage and Metal‐Free Hydrogen Transfer

open access: yesSmall, EarlyView.
Borophane in dual roles: as a reductant in the conversion of levulinic acid to γ‐valerolactone and as a reversible hydrogen reservoir through partial rehydrogenation. ABSTRACT 2D borophene has long been proposed as a promising hydrogen storage material, but experimental demonstrations remain limited to boron hydride sheets derived from MgB2.

Sequential Optimization of Multivariate Metal–Organic Framework Based Biocatalysis

open access: yesSmall, EarlyView.
A sequential Latin hypercube sampling–coupled Bayesian optimization (LHS‐BO) workflow integrates multivariate zirconium‐based metal–organic framework based biocomposite (E‐MOF) design with enzyme biocascade reaction optimization. The optimized E‐MOFs stabilize glucose oxidase and horseradish peroxidase in bioactive conformation, exhibiting high ...

Going Deep into the Surface Chemistry of Carbon Dots: Influence of Functional Groups on the Redox Abilities

open access: yesSmall, EarlyView.
The chemical structure of Carbon Dots (CDs) is still a mystery despite years of study. Herein, we show how CDs with a higher density of surface‐accessible amines display enhanced (photo)redox performance. Electrochemical and thermodynamic analyses confirmed the feasibility of electron transfer, while mechanistic investigations revealed that the ...
