Experimental Evidence for a Metal‐Related Function of a Cyanobactin

Angewandte Chemie International Edition, Volume 65, Issue 25, 15 June 2026.
Cyanobactins such as patellamides are produced by cyanobacteria profusely and have been studied extensively, but almost exclusively for their cytotoxic properties. Discussed is unprecedented experimental evidence for a metal‐related biological function – likely CO2 transport from the ascidian to the cyanobacterial symbiont.

Structural Basis for Nucleobase Activation by the Adenine DNA Glycosylase MutY

ChemBioChem, Volume 27, Issue 11, 15 June 2026.
DNA glycosylase MutY engages its adenine nucleobase substrate in a syn orientation with a catalytic Glu. X‐ray crystal structures of MutY with Glu replaced suggest that a disengaged “on hold” state with anti nucleobase orientation may explain how MutY avoids catastrophic activity at inappropriate adenines.

Cefdinir binding to a class A β-lactamase revealed by serial cryo-crystallography. [PDF]

Acta Crystallogr D Struct Biol
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 ...

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

FEBS Letters, Volume 600, Issue 11, Page 1621-1637, June 2026.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Synthesis of a C‐2 Functionalized l‐Iduronic Acid Derivative as a Candidate Pharmacological Chaperone for MPS II (Hunter Syndrome)

Chemistry – An Asian Journal, Volume 21, Issue 11, 15 June 2026.
A C‐2 functionalized l‐iduronic acid derivative was designed and synthesized as a candidate pharmacological chaperone for iduronate‐2‐sulfatase (IDS), the enzyme involved in the lysosomal storage disease MPS II (Hunter syndrome). The synthesis overcomes significant synthetic challenges associated with manipulations of L‐ido scaffolds.

Isolation and Structural Characterization of Se‐Hügerschoff Intermediates Derived From 4‐Bromoaniline

Journal of Heterocyclic Chemistry, Volume 63, Issue 6, Page 1004-1009, June 2026.
Isolation and characterization of Se‐brominated Hügerschoff intermediates enable structural and mechanistic insight into seleno‐Hügerschoff cyclization to 2‐aminobenzoselenazoles. ABSTRACT A brominated intermediate within the Hügerschoff reaction has long been postulated but never directly observed.

Exploring and Targeting the Connection of Iron and Copper Homeostasis to Neurodegenerative Diseases

MedComm, Volume 7, Issue 6, June 2026.
Iron and copper dyshomeostasis, along with their interactions with key intrinsically disordered proteins (e.g., Aβ, tau, α‐synuclein) have a strong implication in the onset and progression of neurodegenerative diseases, including Alzheimer's disease (AD), Parkinson's disease (PD), Prion diseases (PrDs), Huntington's disease (HD), Wilson's disease (WD),

Investigating the role of a conserved hydrophobic pocket of gp41 in the anti‐HIV activity of fusion inhibitors

Protein Science, Volume 35, Issue 6, June 2026.
Abstract Membrane fusion between HIV and host cells requires interaction between the N‐terminal and C‐terminal repeat regions (NHR and CHR) of the gp41 envelope subunit. A deep hydrophobic pocket (HP) on the surface of NHR is considered crucial in this interaction.
