Engineering of modular polyketide synthases to produce novel polyketides
Current Opinion in Biotechnology, 1998Polyketides are important natural products produced by Actinomycetes and other organisms via the polymerization of coenzyme A-activated carboxylic acids. Modular polyketide synthases are large multifunctional enzymes that direct the biosynthetic process using a dedicated 'module' for each polymerization reaction, which specifies the unit to be ...

Manipulation and Analysis of Polyketide Synthases
2004Publisher Summary This chapter examines the manipulation and analysis of polyketide (PKS) synthases. PKS span a large range of medicinally important com-pounds, such as antibiotics, anticancer agents, immunosuppressants, and cholesterol-lowering agents.

Biosynthesis of polyketides by trans-AT polyketide synthases in Burkholderiales
Critical Reviews in Microbiology, 2019Widely used as drugs and agrochemicals, polyketides are a family of bioactive natural products, with diverse structures and functions. Polyketides are produced by megaenzymes termed as polyketide synthases (PKSs). PKS biosynthetic pathways are divided into the cis-AT PKSs and trans-AT PKSs; a division based mainly on the absence of an acyltransferase ...

Polyketide Synthases: Mechanisms and Models
2006The modular structure of the multienzyme PKSs makes them particularly attractive targets for combinatorial biosynthesis aimed at generating novel polyketide medicines. We are beginning to understand those features of subunit organization and structure and their linking and docking elements, which are critical for productive engineering efforts ...

Cell-free synthesis of polyketides by recombinant erythromycin polyketide synthases
Nature, 1995Modular polyketide synthases (PKSs) are complex multi-enzyme proteins that catalyse the bacterial biosynthesis of many pharmaceutically useful polyketides. The PKSs are organized into a series of modules, each containing the active catalytic sites required for one step in the synthesis process.

Production of a novel polyketide through the construction of a hybrid polyketide synthase
Gene, 1996The lactone rings of the polyketides platenolide and tylactone are synthesized by condensation of acetate-, proprionate-, and butyrate-derived precursors. A hybrid tylactone/platenolide synthase was constructed to determine if the choice of substrate is programmed by the polyketide synthase and to ascertain if a substrate different than that normally ...

Fungal type III polyketide synthases
Nat. Prod. Rep., 2014This article covers the literature on fungal type III polyketide synthases (PKSs) published from 2005 to 2014. Since the first discovery of fungal type III PKS genes in Aspergillus oryzae, reported in 2005, putative genes for type III PKSs have been discovered in fungal genomes.

Non-modular polyketide synthases in myxobacteria
Phytochemistry, 2009Myxobacteria are prolific producers of a wide variety of secondary metabolites. The vast majority of these compounds are complex polyketides which are biosynthesised by multimodular polyketide synthases (PKSs). In contrast, few myxobacterial metabolites isolated to date are derived from non-modular PKSs, in particular type III PKSs. This review reports

Novel applications of plant polyketide synthases
Current Opinion in Chemical Biology, 2012The structurally and mechanistically simple type III polyketide synthases (PKSs) catalyze iterative condensations of CoA thioesters to produce a variety of polyketide scaffolds with remarkably diverse structures and biological activities. By exploiting the enzymes, we combined precursor-directed biosynthesis with nitrogen-containing substrates and ...
