Hybrid macrocyclic peptides unite genetically encoded peptide libraries with the structural complexity of synthetic small molecules. This Review critically analyzes phage‐compatible cyclization and diversification chemistries, highlights emerging opportunities beyond traditional cysteine‐based approaches, and outlines how future advances may enable the

Antifungal peptides in marine invertebrates
A majority of terrestrial and marine organisms use to fend off a wide range of microorganisms, including bacteria and fungi by employing “antimicrobial peptides (AMPs)” that are ribosomally synthesized from proteinogenic amino acids.

ExMODE: A comprehensive resource for extremophile genomic and functional exploration
ExMODE (https://db.genomics.cn/exmode/) integrates 3518 samples to build a unified extremophile resource, which hosts 1.35 billion habitat‐specific non‐redundant genes, 5.25 million representative protein structures, 67,026 metagenome‐assembled genomes (MAGs), and 164,132 biosynthetic gene clusters (BGCs). By combining sequence‐, structure‐, and genome‐

Multi‐omics reveals gastrointestinal metabolic disorder‐induced diarrhea in postpartum dairy cows
Nutritional diarrhea is a pervasive, costly challenge in dairy production. Using integrated metagenomic and metabolomic profiling, we identified coordinated microbial and metabolic alterations across the rumen, hindgut, and serum. In the rumen, enrichment of Prevotella sp.

ISAba1‐mediated crp‐osmC amplification enhances host‐associated fitness in Acinetobacter baumannii
Abstract Acinetobacter baumannii is a pathogen, highly adaptable to both hospital‐ and host‐associated environments. Understanding the genetic mechanisms underlying its adaptability is critical for controlling its persistence. Our study identified the crp‐osmC gene cluster, flanked by ISAba1 elements, as a significant genetic structure undergoing ...

Overexpression of the gouM transporter gene in Streptomyces noursei CK‐15 enhances gougerotin production by 114% and activates silent biosynthetic gene clusters. This finding links transporter activity to metabolite efflux and secondary metabolism, offering a strategy for natural product discovery and strain optimization.

Caffeic acid is a central metabolite in the fungal bioluminescence pathway. We identified and characterized caffeylpyruvate hydrolase from Neonothopanus gardneri (ngarCPH) and demonstrate its ability to hydrolyze fungal oxyluciferin into caffeic and pyruvic acids, confirming a complete and self‐sustained fungal bioluminescence cycle.

The tryptophan prenyltransferase ComQ from Bacillus subtilis 168 can prenylate daptomycin at Trp1
ComQ168 from Bacillus subtilis 168 catalyzes C‐terminal tryptophan farnesylation of ComX to generate a competence‐inducing pheromone. Recombinant ComQ168 also modifies cyclic peptides, including Daptomycin, likely at the N‐terminal tryptophan. Structural modeling highlights a C‐terminal binding region, supporting substrate promiscuity and establishing ...

Efficient rational modification of non-ribosomal peptides by adenylation domain substitution
Non-ribosomal peptide synthases are multimodular enzymes comprised of adenylation (A), condensation (C) and thiolation domains. Here, the authors show that non-ribosomal peptides can be generated solely by A domain substitutions, providing evidence that ...

ABSTRACT After an initial evolution in a reducing environment, life got successively challenged by reactive oxygen species (ROS), especially during the great oxidation event (GOE) that followed the development of photosynthesis. Therefore, ROS are deeply intertwined into the physiological, morphological and transcriptional responses of most present‐day
