Spatial and temporal scales in plant phenotyping for crop water stress assessment: A review
The Plant Phenome Journal, Volume 9, Issue 1, December 2026.Abstract Water stress is a major limiting factor for crop productivity worldwide, and its impacts are intensifying due to climate variability and increasing water scarcity. This review focuses on the spatial and temporal scales in plant phenotyping as a critical approach to improving crop water‐stress assessment and supporting precision water ...

Angewandte Chemie, Volume 138, Issue 44, 26 October 2026.We report the computational design of de novo proteins that bind Mn(salen)‐based complexes (L1) using Rosetta FastDesign and verified by AlphaFold2. After screening, the catalytic activity for the promising design (dnMSBP) toward enantioselective sulfoxidation of thioanisole was optimized based on its crystal structure. With 10 different substrates, we

Multienzyme Cascade Reactions: Compatibility, Cooperativity, and Control
Advanced Synthesis &Catalysis, Volume 368, Issue 21, 3 November 2026.Multienzyme cascade reactions are sequences of telescoped biotransformations that avoid the isolation of intermediates and offer significant efficiency advantages over traditional multistep routes. This review article highlights recent examples of multienzyme cascades and explores how their success depends on the consideration of compatibility ...

Substrate‐Dependent Crosslinking by the Cytochrome P450 From Aminopyruvatide Biosynthesis
Angewandte Chemie, Volume 138, Issue 44, 26 October 2026.Substitutions in the aminopyruvatide precursor peptide altered the C─C linkage formed from a YLY motif by the P450 ApyO to a N─C linkage in a WLY motif. Moreover, constitutional isomers crosslinked by C─C and C─O linkages were formed from YYY or YWY motifs. ABSTRACT Cytochrome P450s catalyze an array of reactions including crosslinking of aromatic side
