Substrate‐Dependent Crosslinking by the Cytochrome P450 From Aminopyruvatide Biosynthesis
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

Recombinant versus native botulinum neurotoxin type A: structural and pharmacodynamic comparison
For the first time, the recombinant core botulinum neurotoxin type A (BoNT/A) expressed in Escherichia coli and nicked in vitro is shown to be structurally identical to native BoNT/A from Clostridium botulinum, enabling direct activity comparison between the recombinant product and the native toxin.Botulinum neurotoxins (BoNTs) are highly potent ...

A potyvirus‐derived virus‐like nanoparticle (VLP) interferes in the transmission by aphids of the non‐circulative plant viruses turnip mosaic virus (TuMV, Potyvirus), zucchini yellow mosaic virus (ZYMV, Potyvirus), and cucumber mosaic virus (CMV, Cucumovirus) is also observed. The construct, that consisted of a fusion between a modified TuMV HC‐Pro and

Aging‐associated NAD+ depletion in hypothalamic neurons shortens primary cilia and disrupts CHMP4B trafficking to lysosomes during lysosomal stress, leading to impaired TRPML1–mediated Ca2+ signaling and lysosomal stress responses. Calorie restriction restores hypothalamic NAD+ levels, ciliary structure, and lysosomal homeostasis, thereby improving ...

Covalent drug discovery: Progress against key targets, emerging strategies and lessons learnt
Abstract Covalent drug discovery is currently experiencing a boom in industrial and academic interest. To date, at least 75 covalent drugs have received regulatory approval, targeting both traditional target classes and more challenging proteins for which other approaches failed. In many cases, unique aspects of covalent targeting are essential for the

Prepartum Heat Stress Dysregulates Immune Resilience in Postpartum Dairy Cows
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.

Adenylation Domain Engineering Enables Biosynthesis of an Improved Polymyxin Antibiotic
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
