Hemiacetal-less rapamycin derivatives designed and produced by genetic engineering of a type I polyketide synthase

Scientific Reports, 2021
Engineering polyketide synthases is one of the most promising ways of producing a variety of polyketide derivatives. Exploring the undiscovered chemical space of this medicinally important class of middle molecular weight natural products will aid in the

First genome sequence of a European Alternaria brassicae isolate and genes involved in early development of alternaria leaf spot on Brassica juncea

Pest Management Science, EarlyView.
This article reports the first genome sequence of a UK Alternaria brassicae isolate. Dual RNA‐sequencing profiling of A. brassicae‐infected Brassica juncea leaves identified differentially expressed genes involved in pathogenicity and host response pathways in moderately resistant Sej‐2 (2) and moderately susceptible Pusa Jaikisan cultivars.

Bioactive Natural Products in Cardiovascular Disease: Focus on Thrombotic Events

Phytotherapy Research, EarlyView.
An overview of the role of natural products (NP) in cardiovascular disease prevention, highlighting key mechanisms of action: including antiplatelet, antithrombotic, anti‐inflammatory, and antioxidant effects. Additionally, it illustrates the integration of diet–drug interactions, nutritional epigenetics, and the role of artificial intelligence in ...

Dissecting and exploiting intermodular communication in polyketide synthases

, 1999
Modular polyketide synthases catalyze the biosynthesis of medicinally important natural products through an assembly-line mechanism. Although these megasynthases display very precise overall selectivity, we show that their constituent modules are ...

A horizontally transferred bacterial gene for pantothenic acid biosynthesis regulates diapause and reproduction in the spider mite Amphitetranychus viennensis

Insect Science, EarlyView.
A bacterial‐derived AvPBL gene encoding a pantothenate‐β‐alanine ligase was identified in Amphitetranychus viennensis. RNAi silencing of AvPBL reduced pantothenic acid production, impairing reproduction and diapause induction, while pantothenic acid supplementation rescued these phenotypes.

A Wagner–Meerwein‐Like Rearrangement Generates a Vinyl Group in the Biosynthesis of the Polychlorinated Lipopeptides Fischerazoles

Angewandte Chemie, Volume 138, Issue 37, 7 September 2026.
The fischerazoles, unusual cyanobacterial chlorinated lipopeptides are reported. During their biosynthesis, a linear fatty acyl‐acyl carrier protein (ACP) precursor is rearranged through the action of the S‐adenosyl‐methionine (SAM)‐dependent methyltransferase FshF, to generate a pendant vinyl group.

A novel class of plant type III polyketide synthase involved in orsellinic acid biosynthesis from Rhododendron dauricum

Frontiers in Plant Science, 2016
Rhododendron dauricum L. produces daurichromenic acid, the anti-HIV meroterpenoid consisting of sesquiterpene and orsellinic acid moieties. To characterize the enzyme responsible for orsellinic acid biosynthesis, a cDNA encoding a novel polyketide ...

Natural product‐derived TRPM7 channel inhibitors in neurological injury: Mechanisms, pharmacological potential and translational challenges

British Journal of Pharmacology, EarlyView.
Disruption of intracellular ionic homeostasis is a convergent pathological feature across diverse neurological injuries and disorders, including ischaemic and haemorrhagic stroke, hypoxic–ischaemic brain injury, traumatic brain injury, epilepsy and brain tumour.

The architecture of polyketide synthases

, 2023
Since the discovery of penicillin over a century ago, secondary metabolites from all kingdoms of life have proven to be of high medical value. One class of proteins prevalent in the production of secondary metabolites are polyketide synthases (PKSs).
