Diverse Bacterial PKS Sequences Derived From Okadaic Acid-Producing Dinoflagellates

open access: yesMarine Drugs, 2008
Okadaic acid (OA) and the related dinophysistoxins are isolated from dinoflagellates of the genus Prorocentrum and Dinophysis. Bacteria of the Roseobacter group have been associated with okadaic acid producing dinoflagellates and have been previously ...

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

open access: yesEnvironmental 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 ...

Mechanistic Insights Into the Biosynthesis of Pseurotin A in Aspergillus fumigatus

open access: yesSmall Structures
The biosynthesis of pseurotin A, a fungal metabolite with antibiotic and immunosuppressive properties, involves a group of enzymes, including a polyketide‐nonribosomal peptide synthase (PKS‐NRPS), PsoA, and a bifunctional enzyme, PsoF. PsoA consists of a

Methyl Jasmonate Seed Priming Mitigates the Defence‐Growth Trade‐Off and Tailors Plant Response to Specific Pests

open access: yesPlant, Cell &Environment, Volume 49, Issue 10, Page 7558-7574, October 2026.
ABSTRACT Seed defence priming is emerging as a novel, cost‐efficient and environmentally safe tool for pest management. It has been proposed as a means to uncouple the defence‐growth trade‐off in plants by enhancing defence responses with minimal fitness costs, but the mechanisms underlying this role remain elusive.

The aquastatin biosynthetic gene cluster encodes a versatile polyketide synthase capable of synthesising heteromeric depsides with diverse alkyl side chains [PDF]

open access: yes
Depsides have garnered substantial interest due to the diverse biological activities exhibited by members of this class. Among these are the antibacterial aquastatins, glycosylated heteromeric depsides formed through the condensation of orsellinic acid ...

Tropinone synthesis via an atypical polyketide synthase and P450-mediated cyclization

open access: yesNature Communications, 2018
Tropinone is an intermediate in the biosynthesis of tropane alkaloids. Here, the authors discovered the enzymes AbPYKS and AbCYP82M3, a non-canonical polyketide synthase and a cytochrome P450, that work sequentially to form tropinone from N-methyl-Δ1 ...

Repurposing a Fully-Reducing Polyketide Synthase for 2-Methyl Guerbet-like Lipid Production [PDF]

open access: yes
In Nature, thousands of diverse and bioactive polyketides are assembled by a family of multifunctional, “assembly line” enzyme complexes called Polyketide Synthases (PKS).

In silico identification of Capsicum type III polyketide synthase genes and expression patterns in Capsicum annuum

open access: yesOpen Life Sciences, 2020
Studies have shown that abundant and various flavonoids accumulate in chili pepper (Capsicum), but there are few reports on the genes that govern chili pepper flavonoid biosynthesis. Here, we report the comprehensive identification of genes encoding type
