Stereochemische Entschlüsselung der Strobilurin‐PKS enthüllt die komplexe biosynthetische Logik des iterativen Aufbaus eines EZE‐Triens

Angewandte Chemie, Volume 138, Issue 4, 22 January 2026.
Die iterative Strobilurin‐PKS baut ein bemerkenswertes EZE‐Trien auf, indem es seine S‐tereoselektvität während der Synthese variiert. Die stereoselektive 2R‐Methylierung des Triketid‐Intermediats durch die C‐terminale C‐Methyltransferase‐Domäne induziert die KR‐ und DH‐Domänen ihre native Stereoselektivität umzukehren und ein Z‐konfiguriertes ...

Ko‐Assemblierungen regulieren die katalytische Aktivität von Peptidfibrillen

Angewandte Chemie, Volume 138, Issue 2, 9 January 2026.
Katalytische selbstassemblierende Peptide (kSAPs) bilden Fibrillen, die die Retro‐Aldol‐Reaktion von Methodol katalysieren. Die Ko‐Assemblierung mit inaktiven Peptiden reguliert die katalytische Aktivität, indem sie die Zugänglichkeit des Substrats und den Abstand zum nukleophilen Lysin verändert.

Core‐Shell Functionalized Block Copolymer Micelles: A Versatile Approach Toward One‐Pot Two‐Step Tandem Reactions

ChemCatChem, Volume 17, Issue 23, December 8, 2025.
We report the synthesis of core/shell functionalized block copolymer micelles functionalized with sulfonic acid in the hydrophilic shell and l‐proline in the hydrophobic core. These micelles were successfully applied in aqueous medium in a one‐pot tandem reaction consisting of a sulfonic acid‐based acetal cleavage followed by an l‐proline‐catalyzed ...

Exploring Gelatin‐A and Mouse Proline‐Rich Protein 5 as Probes for Wine Polyphenol Analysis by Quartz Crystal Microbalance with Dissipation Monitoring

Advanced Sensor Research, Volume 4, Issue 8, August 2025.
This study presents a novel strategy for the detection of polyphenols in wine. By combining Quartz Crystal Microbalance with Dissipation Monitoring and original functionalization strategies, Gelatin A from porcine skin and Mouse Proline‐Rich Protein 5, polyphenols are successfully detected directly in wine without any prior sample preparation ...
