Streptavidins Coordinate Biotin Sequestration and Self‐Resistance Within a Biotin‐Pathway Antibiotic Network

open access: yesAdvanced Science, Volume 13, Issue 46, 17 August 2026.
A conserved genomic region between two streptavidin genes in Streptomyces packages biosynthetic gene clusters for diverse biotin‐pathway antibiotics: acidomycin, stravidin, the new non‐proteinogenic amino acid ANDA, and the new BioA inhibitor α‐methyl‐KAPA.

Structural basis of nonribosomal peptide macrocyclization in fungi [PDF]

open access: yesNature Chemical Biology, 2016
Nonribosomal peptide synthetases (NRPSs) in fungi biosynthesize important pharmaceutical compounds, including penicillin, cyclosporine and echinocandin. To understand the fungal strategy of forging the macrocyclic peptide linkage, we determined the crystal structures of the terminal condensation-like (CT) domain and the holo thiolation (T)-CT complex ...

Molecular basis for depsipeptide HDAC inhibitor combinatorial biosynthesis

open access: yesNature Communications
Polyketides and nonribosomal peptides are important natural product classes with wide-ranging medical and agricultural applications. The analogous enzymatic logic employed by bacterial modular polyketide synthases (PKSs) and nonribosomal peptide ...

Microbial Oxidative Stress in Food Fermentations: A Comprehensive Review

open access: yeseFood, Volume 7, Issue 4, August 2026.
Oxidative stress has a dual role in food fermentations: low ROS supports adaptive signaling, whereas excessive ROS causes cellular damage and process inhibition. Managing redox state as a controllable process variable can improve fermentation robustness and final food quality.

Deciphering the Function and Structure of PA1216 as an S‐Adenosyl‐l‐Methionine Binding Protein Using Differential Scanning Fluorimetry and Circular Dichroism

open access: yesProtein Science, Volume 35, Issue 8, August 2026.
Abstract Microbes produce bioactive secondary metabolites as toxins, pigments, or virulence factors. These specialized compounds are produced by nonribosomal peptide synthetases (NRPS), polyketide synthases (PKS), or hybrid NRPS/PKS pathways. The genes encoding NRPS and PKS reside in biosynthetic gene clusters (BGCs), some of which have no identified ...

Efficient rational modification of non-ribosomal peptides by adenylation domain substitution

open access: yesNature Communications, 2020
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 ...

Beneath the Bark: Molecular Determinants of Adaptation and Infection in Bacterial Pathogens of Woody Hosts

open access: yesMolecular Plant Pathology, Volume 27, Issue 8, August 2026.
Bacterial pathogens colonise woody hosts by integrating metabolic adaptation, effector‐mediated immune suppression, cell wall remodelling and EPS‐ and toxin‐supported persistence. ABSTRACT Bacterial pathogens of woody plants represent a pervasive yet underexplored threat to global agriculture and forestry, causing devastating diseases in fruit trees ...

Plastic Diets Drive Microbiome and Metabolic Reprogramming in Wax Moth Larvae (Achroia grisella)

open access: yesArchives of Insect Biochemistry and Physiology, Volume 122, Issue 3, July 2026.
Wax moth larvae (Achroia grisella) can consume LDPE and PLA, triggering polymer‐specific restructuring of the gut microbiome and host metabolism. LDPE feeding enriches Bacillus spp. and is associated with shifts in carbohydrate and amino‐acid pathways consistent with hydrocarbon processing, whereas PLA feeding enriches Enterococcus spp.

Genome mining unearths a hybrid nonribosomal peptide synthetase-like-pteridine synthase biosynthetic gene cluster

open access: yeseLife, 2017
Nonribosomal peptides represent a large class of metabolites with pharmaceutical relevance. Pteridines, such as pterins, folates, and flavins, are heterocyclic metabolites that often serve as redox-active cofactors.

The Pharmacological Potential of Nonribosomal Peptides from Marine Sponge and Tunicates

open access: yesFrontiers in Pharmacology, 2016
Marine biodiversity is recognized by a wide and unique array of fascinating structures. The complex associations of marine microorganisms, especially with sponges, bryozoans, and tunicates, make it extremely difficult to define the biosynthetic source of
