Structure and Biosynthesis of Xenoamicins from Entomopathogenic Xenorhabdus [PDF]

Chemistry – A European Journal, 2013
AbstractDuring the search for novel natural products from entomopathogenic Xenorhabdus doucetiae DSM17909 and X. mauleonii DSM17908 novel peptides named xenoamicins were identified in addition to the already known antibiotics xenocoumacin and xenorhabdin. Xenoamicins are acylated tridecadepsipeptides consisting of mainly hydrophobic amino acids.

PoolSeq Genome‐Wide Association Studies and Microbial Signature Analyses Identify Novel Candidates Associated With Pyrethroid Resistance Evolution in Anopheles funestus in Cameroon

Molecular Ecology, Volume 35, Issue 1, January 2026.
ABSTRACT Intensification of insecticide resistance in malaria vectors is undermining efforts to sustain control strategies. The evolutionary features underlying such exacerbation in major vector such as Anopheles funestus are only partially understood.

Comparative Genomics and Pathogenicity Analysis of Two Bacterial Symbionts of Entomopathogenic Nematodes: The Role of the GroEL Protein in Virulence

Microorganisms, 2022
Bacteria of the genera Xenorhabdus and Photorhabdus are symbionts of entomopathogenic nematodes. Despite their close phylogenetic relationship, they show differences in their pathogenicity and virulence mechanisms in target insects.

Pangenome Analysis of the Plant Pathogen Pseudomonas syringae Reveals Unique Natural Products for Niche Adaptation

Angewandte Chemie, Volume 137, Issue 25, June 17, 2025.
A pangenome analysis of the plant pathogen Pseudomonas syringae reveals two novel natural product families that facilitate niche adaptation. Comprehensive genomic and chemical analyses uncover unique biosynthetic gene clusters linked to host specificity and environmental fitness.

The insect pathogenic bacterium Xenorhabdus innexi has attenuated virulence in multiple insect model hosts yet encodes a potent mosquitocidal toxin

BMC Genomics, 2017
Background Xenorhabdus innexi is a bacterial symbiont of Steinernema scapterisci nematodes, which is a cricket-specialist parasite and together the nematode and bacteria infect and kill crickets. Curiously, X.

Entomopathogenic nematode-associated microbiota: from monoxenic paradigm to pathobiome

Microbiome, 2020
Background The holistic view of bacterial symbiosis, incorporating both host and microbial environment, constitutes a major conceptual shift in studies deciphering host-microbe interactions. Interactions between Steinernema entomopathogenic nematodes and

Comparative analysis of P2-type remnant prophage loci in Xenorhabdus bovienii and Xenorhabdus nematophila required for xenorhabdicin production [PDF]

FEMS Microbiology Letters, 2012
The xnp1 remnant P2-type prophage of Xenorhabdus nematophila produces xenorhabdicin that is active against closely related species. Xenorhabdicin had not been characterized previously in other Xenorhabdus species. Here, we show xenorhabdicin production in six different strains of Xenorhabdus bovienii. The sequenced genome of X.

Structural and dynamic roles of tandem acyl carrier proteins in aryl polyene biosynthesis in carbapenem‐resistant Acinetobacter baumannii

Protein Science, Volume 34, Issue 12, December 2025.
Abstract Aryl polyenes (APEs) are critical secondary metabolites in gram‐negative pathogens, synthesized by polyketide synthases that rely on acyl carrier proteins (ACPs) as essential cofactors. Despite their importance, the structural and functional dynamics of tandem ACPs—ApeE and ApeF—have remained largely uncharacterized.

Origin and characterization of cyclodepsipeptides: Comprehensive structural approaches with focus on mass spectrometry analysis of alkali‐cationized molecular species

Mass Spectrometry Reviews, Volume 44, Issue 6, Page 1013-1098, November/December 2025.
Abstract Cyclodepsipeptides (CDPs) represent a huge family of chemically and structurally diverse molecules with a wide ability for molecular interactions. CDPs are cyclic peptide‐related natural products made up of both proteinogenic and nonproteinogenic amino acids linked by amide and ester bonds.
