Elucidating the Diversity and Potential Function of Nonribosomal Peptide and Polyketide Biosynthetic Gene Clusters in the Root Microbiome

open access: yesmSystems, 2020
Polyketides (PKs) and nonribosomal peptides (NRPs) are two microbial secondary metabolite (SM) families known for their variety of functions, including antimicrobials, siderophores, and others.

Erubescensoic Acid, a New Polyketide and a Xanthonopyrone SPF-3059-26 from the Culture of the Marine Sponge-Associated Fungus Penicillium erubescens KUFA 0220 and Antibacterial Activity Evaluation of Some of Its Constituents

open access: yesMolecules, 2019
A new polyketide erubescensoic acid (1), and the previously reported xanthonopyrone, SPF-3059-26 (2), were isolated from the uninvestigated fractions of the ethyl acetate crude extract of the marine sponge-associated fungus Penicillium erubescens ...

Bioactive Compounds from Terrestrial and Marine-Derived Fungi of the Genus Neosartorya †

open access: yesMolecules, 2022
Fungi comprise the second most species-rich organism group after that of insects. Recent estimates hypothesized that the currently reported fungal species range from 3.5 to 5.1 million types worldwide. Fungi can grow in a wide range of habitats, from the

The Stereochemistry of Complex Polyketide Biosynthesis by Modular Polyketide Synthases

open access: yesMolecules, 2011
Polyketides are a diverse class of medically important natural products whose biosynthesis is catalysed by polyketide synthases (PKSs), in a fashion highly analogous to fatty acid biosynthesis. In modular PKSs, the polyketide chain is assembled by the successive condensation of activated carboxylic acid-derived units, where chain extension occurs with ...

Biosynthesis of fungal polyketides

open access: yes, 2018
Fungal polyketides comprise of a large group of structurally diverse compounds with a wide range of biological activities. These compounds are biosynthesised by Type I iterative polyketide synthases (PKS) which can be further defined as non-reducing (nr),

Comprehensive Description of Fusarium graminearum Pigments and Related Compounds

open access: yesFoods, 2018
Several studies have explored in depth the biochemistry and genetics of the pigments present in Fusarium graminearum, but there is a need to discuss their relationship with the mold’s observable surface color pattern variation throughout its ...

Structural control of polyketide formation in plant-specific polyketide synthases [PDF]

open access: yesChemistry & Biology, 2000
Polyketide synthases (PKSs) generate molecular diversity by utilizing different starter molecules and by controlling the final length of the polyketide. Although exploitation of this mechanistic variability has produced novel polyketides, the structural foundation of this versatility is unclear. Plant-specific PKSs are essential for the biosynthesis of

Medicinal Chemistry of Annonaceous Acetogenins: Design, Synthesis, and Biological Evaluation of Novel Analogues

open access: yesMolecules, 2009
Most Annonaceous acetogenins are characterized by between one and three THF ring(s) with one or two flanking hydroxyl group(s) in the center of a C32/34 fatty acid, and the terminal carboxylic acid is combined with a 2-propanol unit to form an α,β ...
