Ammonification Process Is Limited by Transformation of Medium Molecular Weight Nitrogenous Organics but Not Hydrolysis of Proteins

Advanced Science, EarlyView.
A multi‐level analytical framework, integrating protein‐level persistence analysis, nontargeted HRMS formula tracking, peptide‐level proteomics, and targeted monomer quantification under varying redox conditions, together with FMO calculations reveal that ammonification is limited by medium molecular weight nitrogenous multimers.

Synthesis of Ladder and Flexible Polysulfonimides Directly From Anionic Monomers: Investigating Structure–Property Convergence in Succinonitrile–Polymer Electrolyte Blends

Angewandte Chemie, EarlyView.
Direct synthesis of sulfonimide‐based polymers of intrinsic microporosity enables comparison with compositionally similar flexible analogs. Incorporation of a common pore‐filling transport medium drives these fundamentally different polymer architectures toward similar bulk conductivity and mechanical properties while revealing distinct microscopic ion‐

Adenylation Domain Engineering Enables Biosynthesis of an Improved Polymyxin Antibiotic

Angewandte Chemie, EarlyView.
To enable incorporation of l‐2‐aminodecanoic acid into polymyxin by fermentation, a single Trp‐to‐Ala substitution is rationally introduced into the adenylation‐domain residue of its nonribosomal peptide synthetase (NRPS) and efficiently switches substrate selectivity. The engineered strain produces biologically active Ada‐polymyxin, demonstrating that

Metabolomic Mapping of Greek Olive Leaves by Untargeted NMR-Based Profiling and LC-HRMS Dereplication. [PDF]

Anal Sci Adv
ABSTRACT Olive tree leaves are phytochemically rich yet insufficiently valorised in terms of systematic cultivar‐based characterisation and exploitation, and are an abundant olive industry side‐product. This study represents the first large‐scale metabolome mapping based on 340 leaf extracts from five major Greek cultivars (Amfissis, Koroneiki, Manaki,
