Molecular Microbiology, Volume 126, Issue 5, Page 503-518, November 2026.YdcI, a LysR‐type transcription regulator in Escherichia coli, regulates loci like iraP and mqo. Its expression is induced by (p)ppGpp under stress conditions, and protein levels rise during mid‐exponential growth, connecting its role to stress response and metabolism control. ABSTRACT YdcI, a LysR‐type transcription regulator, has been associated with

Cysteine Thioaldehydes: Photolytic Generation, Reactivity, and Biological Implications
Angewandte Chemie, Volume 138, Issue 41, 5 October 2026.Photolysis of cysteine phenacylsulfides bearing non‐conjugating electron‐withdrawing substituents leads to high conversions into cysteine thioaldehydes through a Norrish type‐II pathway. This methodology enabled the study of the aqueous reactivity of these important biosynthetic intermediates, which, depending on peptide sequence, pH and buffer ...

Prepartum Heat Stress Dysregulates Immune Resilience in Postpartum Dairy Cows
The FASEB Journal, Volume 40, Issue 20, 31 October 2026.Increasing environmental temperatures pose a major challenge to animal welfare by inducing heat stress and increasing the incidence of disease. Immune resilience is essential for maintaining animal health; however, the mechanisms linking heat stress to immune dysfunction and disease remain unclear.

Angewandte Chemie, Volume 138, Issue 41, 5 October 2026.We present a foldamer strategy to downsize the histone H3‐H4 quaternary structure into high‐affinity, medium‐sized binders (∼2 kDa) for the histone chaperone ASF1. Our peptide‐oligourea chimeras, designed through structure‐guided optimization and foldamer chemistry, recapitulate the natural H3‐H4 dimer binding mode while demonstrating plasma stability ...

Photochemical Reaction Discovery Enabled by the Dynamic Speciation of Copper Complexes
Angewandte Chemie, Volume 138, Issue 41, 5 October 2026.A strategy for accelerated photochemical reaction discovery is reported that harnesses the dynamic speciation of copper complexes, driven by their labile metal–ligand bonds. This platform simplifies reaction screening by combining an earth‐abundant copper(II) salt with commercially available ligands, which reversibly generate multiple catalytic species
