A Revised Model for Muscarine Biosynthesis Involving Lysine Trimethylation

Angewandte Chemie, Volume 138, Issue 24, 8 June 2026.
The fatal mushroom toxin l‐(+)‐muscarine is one of the most prominent natural products. We elucidated its biosynthetic origin in the sweating mushroom Collybia rivulosa based on incorporation of stable isotope‐labeled compounds and extensive mass spectrometric analyses.

Surveying the potential of secreted antimicrobial peptides to enhance plant disease resistance.

Frontiers in Plant Science, 2015
Antimicrobial peptides (AMPs) are natural products found across diverse taxa as part of the innate immune system against pathogen attacks. Some AMPs are synthesised through the canonical gene expression machinery and are called ribosomal AMPs. Other AMPs

Small Spatial Scale Drivers of Secondary Metabolite Biosynthetic Diversity in Environmental Microbiomes

mSystems, 2023
In the search for novel drug candidates, diverse environmental microbiomes have been surveyed for their secondary metabolite biosynthesis potential, yet little is known about the biosynthetic diversity encoded by divergent microbiomes from different ...

T2T Genome Assembly and Multi‐Omics Data Reveal Terrestrial Adaptation and Mucus Biosynthesis in Tropical Leatherleaf Slug (Laevicaulis alte)

Advanced Science, EarlyView.
A gap‐free genome assembly and multi‐omics comparison of the terrestrial slug Laevichaulis alte with an aquatic relative reveal that expansion of the VEGF family orchestrates mucus production, lipid metabolism, and immune defense—highlighting key molecular innovations for conquering life on land.

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

Environmental Toxicology, EarlyView.
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 ...

Dereplication and de novo sequencing of nonribosomal peptides [PDF]

Nature Methods, 2009
Nonribosomal peptides (NRPs) are of great pharmacological importance, but there is currently no technology for high-throughput NRP 'dereplication' and sequencing. We used multistage mass spectrometry followed by spectral alignment algorithms for sequencing of cyclic NRPs. We also developed an algorithm for comparative NRP dereplication that establishes

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.

Mining the Yucatan Coastal Microbiome for the Identification of Non-Ribosomal Peptides Synthetase (NRPS) Genes

Toxins, 2020
Prokaryotes represent a source of both biotechnological and pharmaceutical molecules of importance, such as nonribosomal peptides (NRPs). NRPs are secondary metabolites which their synthesis is independent of ribosomes.

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
