Janus Reactivity of a Mononuclear Non‐Heme Iron(III)‐Peroxo Complex Toward Indole Oxidation
The iron(III)‐peroxo complex [FeIII(O2)(12‐TMC)]+ exhibits bifurcating pathways in indole oxidation. N─H indoles undergo N─H H‐atom abstraction, supported by a KIE of 5.2 for N─H/N–D 2,3‐dimethylindoles, whereas N‐methylindoles react via electrophilic addition of the iron‐peroxo group to the C2–C3 double bond of the indole ring, forming iron ...

This study reveals that sampling strategy (i.e., sampling size and approach) is a foundational prerequisite for building accurate and generalizable AI models in peptide discovery. Reaching a threshold of 7.5% of the total tetrapeptide sequence space was essential to ensure reliable predictions.

Noncanonical Peloruside A Biosynthesis by an Uncultivated Verrucomicrobiota Symbiont
Noncanonical biochemistry of the peloruside PKS characterized in this work, comprising double bond generation by a noncanonical tridomain (blue), acetyl‐CoA recycling (orange), and proofreading systems (purple and yellow). The Z‐double bond is installed by TEB1 through O‐acetylation and acetate elimination. The acyl ligase PelB (AL, orange) selectively

ABSTRACT Background Patients with chronic rhinosinusitis with nasal polyps (CRSwNP) exhibit heterogeneous responses to oral glucocorticoids (GCs), but the biological basis of this variability remains unclear. Objective To identify gut microbiome‒plasma metabolomic signatures associated with GC responsiveness in CRSwNP patients and to compare their ...

Cysteine Thioaldehydes: Photolytic Generation, Reactivity, and Biological Implications
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 ...
