Systematic analysis of the kalimantacin assembly line NRPS module using an adapted targeted mutagenesis approach [PDF]

, 2015
Kalimantacin is an antimicrobial compound with strong antistaphylococcal activity that is produced by a hybrid trans-acyltransferase polyketide synthase/nonribosomal peptide synthetase system in Pseudomonas fluorescens BCCM_ID9359.

Early‐Onset Digestive System Cancers: Risk Factors and Clinicopathological and Molecular Features Across Organ Sites

Cancer Science, EarlyView.
Shared risk factors, clinical features, and tumor characteristics across multiple early‐onset cancer types are shown in this Graphical Abstract. Integrative approaches combining molecular pathology, oncology, and population sciences offer opportunities to clarify underlying mechanisms and help us develop preventive strategies for early‐onset cancers ...

Type I polyketide synthase requiring a discrete acyltransferase for polyketide biosynthesis [PDF]

Proceedings of the National Academy of Sciences, 2003
Type I polyketide synthases (PKSs) are multifunctional enzymes that are organized into modules, each of which minimally contains a β-ketoacyl synthase, an acyltransferase (AT), and an acyl carrier protein. Here we report that the leinamycin (LNM) biosynthetic gene cluster from Streptomyces atroolivaceus S-140 ...

Enzymatic synthesis of bioactive quinolones and (thio)coumarins by fungal type III polyketide synthases

The FEBS Journal, EarlyView.
Quinolones are valuable scaffolds for drug discovery but are rare in nature. Here, we show that two fungal enzymes, AthePKS and FerePKS, can generate 2‐quinolones and two additional heteroaromatic scaffolds. Using AthePKS, we designed an artificial enzymatic cascade towards an antimicrobial quinolone from a simple precursor and implemented it in E ...

Direct evidence that the rifamycin polyketide synthase assembles polyketide chains processively [PDF]

Proceedings of the National Academy of Sciences, 1999
The assembly of the polyketide backbone of rifamycin B on the type I rifamycin polyketide synthase (PKS), encoded by the rifA–rifE genes, is terminated by the product of the rifF gene, an amide synthase that releases the completed undecaketide as its macrocyclic lactam. Inactivation of

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

Transcriptomic characterisation and genomic glimpse into the toxigenic dinoflagellate Azadinium spinosum, with emphasis on polykeitde synthase genes [PDF]

, 2015
Background: Unicellular dinoflagellates are an important group of primary producers within the marine plankton community. Many of these species are capable of forming harmful algae blooms (HABs) and of producing potent phycotoxins, thereby causing ...

Convergence and parallelism in the evolution of plant metabolism

Journal of Integrative Plant Biology, EarlyView.
Similar traits in different organisms may originate from shared ancestry or evolve independently. The terminology used to define phenotypic similarity is often confusing. This review attempts to clarify the definitions and present examples from plant domestication and specialized metabolism to explain how complex traits evolve repeatedly in plants ...

The malonyl/acetyl-transferase from murine fatty acid synthase is a promiscuous engineering tool for editing polyketide scaffolds

Communications Chemistry
Modular polyketide synthases (PKSs) play a vital role in the biosynthesis of complex natural products with pharmaceutically relevant properties. Their modular architecture makes them an attractive target for engineering to produce platform chemicals and ...
