Chemistry – A European Journal, EarlyView.A combination of molecular dynamics and quantum mechanics calculations shows that substrate is tightly bound inside the enzyme structure that enables two successive catalytic cycles with dioxygen and α‐ketoglutarate with an initial desaturation followed by hydrogen abstraction and decarboxylation steps to form an isonitrile substituent.

C‐Terminal Functionalization Methods of Amino Acids, Peptides, and Proteins
Chemistry – A European Journal, EarlyView.C‐terminal functionalization offers powerful routes to peptide and protein diversification, yet epimerization, hydrolysis, and selectivity remain key challenges. This Review surveys enzymatic, decarboxylative, and condensation strategies, highlighting advances toward chemo‐ and regioselective, protecting‐group‐free, atom‐efficient methods applicable to

Chemistry – A European Journal, EarlyView.A series of N‐acetylmuramic acid (MurNAc)‐based electrophilic inhibitors targeting Ape esterase was synthesized. Their inhibitory potency ranged from micromolar to submillimolar. The study probed binding contributions of stem peptide extension, replacing the anomeric methyl group with a benzyl, and α‐fluorination of the carbonyl to enhance ...

Selective Formation of a 1,2‐Diborane(4) and Alcohol‐Driven B─B Bond Cleavage to Generate H2
Chemistry – A European Journal, EarlyView.Diborane(4) chemistry reveals unusual reactivity of electron‐deficient p‐block compounds. Reaction of B2Cat2 (Cat = benzene‐1,2‐diolate) with mesityllithium (MesLi; Mes = 2,4,6‐trimethylphenyl) gives a rare 1,2‐diborane(4) featuring a catecholate ligand. Alcoholysis cleaves the B─B bond and ultimately generates H2.

Critical mineral removal from mining‐impacted waters using microalgal biomass
The Canadian Journal of Chemical Engineering, EarlyView.Abstract Rising demand for critical minerals has led to increased mining and mineral processing activities, resulting in the release of metal‐contaminated waters requiring treatment. Conventional treatment methods, such as lime neutralization, effectively precipitate metals; however, they are less effective at low metal concentrations and produce large
