Hybrid Macrocyclic Peptides — Synthetic Strategies to Diversify and Cyclize Peptide Libraries in Phage Display Selections

Chemistry – A European Journal, EarlyView.
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

ExMODE: A comprehensive resource for extremophile genomic and functional exploration

iMetaOmics, EarlyView.
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‐

Delftibactin-A, a Non-ribosomal Peptide With Broad Antimicrobial Activity

Frontiers in Microbiology, 2019
The rapid emergence of drug resistant bacteria is occurring worldwide, outpacing the development of new antibiotics. It is known that some of the main sources of antibiotics are the bacteria themselves, many of which are secondary metabolites of Gram ...

Caffeylpyruvate hydrolase from the bioluminescent fungus Neonothopanus gardneri is the key recycling enzyme in the fungal bioluminescence pathway

The FEBS Journal, EarlyView.
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

The FEBS Journal, EarlyView.
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 ...

Evolutionary Conserved and Divergent Responses to Copper Zinc Superoxide Dismutase Inhibition in Plants

Plant, Cell &Environment, EarlyView.
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

Cyanopeptide Mixtures Induce Variable Synergistic and Antagonistic Effects Across Diverse Human Cell Lines

Environmental Toxicology, Volume 41, Issue 10, Page 807-821, October 2026.
ABSTRACT Cyanobacterial harmful algal blooms (cyanoHABs) threaten human, animal, and ecosystem health and safety through production of toxic secondary metabolites. Microcystis, a cosmopolitan bloom‐forming cyanobacterial genus, is well‐known for producing hepatotoxic microcystins (MCs), but it can produce many other bioactive cyanopeptides, such as ...
