Mining microbial genomes for new natural products and biosynthetic pathways [PDF]

open access: yes, 2008
Analyses of microbial genome sequences have revealed numerous examples of ‘cryptic’ or ‘orphan’ biosynthetic gene clusters, with the potential to direct the production of novel, structurally complex natural products.

The structural basis of N-acyl-α-amino-β-lactone formation catalyzed by a nonribosomal peptide synthetase

open access: yesNature Communications, 2019
The antimicrobial β-lactone obafluorin is produced by a Nonribosomal Peptide Synthetase (NRPS). Here the authors present the crystal structure of the obafluorin NRPS and develop a reconstitution assay that allows them to analyse product formation from ...

Berberine bridge enzyme-like oxidase-catalysed double bond isomerization acts as the pathway switch in cytochalasin synthesis

open access: yesNature Communications, 2022
Cytochalasans are a large family of fungal polyketide-nonribosomal peptide hybrid natural products that exhibit important pharmaceutical activities, but the mechanism of conversion of the monocytochalasans to the polycyclic, fused analogues is unclear ...

The Nonribosomal Peptide Valinomycin: From Discovery to Bioactivity and Biosynthesis

open access: yesMicroorganisms, 2021
Valinomycin is a nonribosomal peptide that was discovered from Streptomyces in 1955. Over the past more than six decades, it has received continuous attention due to its special chemical structure and broad biological activities.

Designing and implementing an assay for the detection of rare and divergent NRPS and PKS clones in European, Antarctic and Cuban soils [PDF]

open access: yes, 2015
The ever increasing microbial resistome means there is an urgent need for new antibiotics. Metagenomics is an underexploited tool in the field of drug discovery. In this study we aimed to produce a new updated assay for the discovery of biosynthetic gene

Diversity of Linear Non-Ribosomal Peptide in Biocontrol Fungi

open access: yesJournal of Fungi, 2020
Biocontrol fungi (BFs) play a key role in regulation of pest populations. BFs produce multiple non-ribosomal peptides (NRPs) and other secondary metabolites that interact with pests, plants and microorganisms. NRPs—including linear and cyclic peptides (L-

Structural and Functional Insights into a Peptide Bond-Forming Bidomain from a Nonribosomal Peptide Synthetase [PDF]

open access: yes, 2007
SummaryThe crystal structure of the bidomain PCP-C from modules 5 and 6 of the nonribosomal tyrocidine synthetase TycC was determined at 1.8 Å resolution.

Terpenoid Biosynthesis Dominates among Secondary Metabolite Clusters in Mucoromycotina Genomes

open access: yesJournal of Fungi, 2021
Early-diverging fungi harbour unprecedented diversity in terms of living forms, biological traits and genome architecture. Before the sequencing era, non-Dikarya fungi were considered unable to produce secondary metabolites (SM); however, this ...

Chapter 14 Biosynthesis of Nonribosomal Peptide Precursors

open access: yes, 2009
Nonribosomal peptides are natural products typically of bacterial and fungal origin. These highly complex molecules display a broad spectrum of biological activities, and have been exploited for the development of immunosuppressant, antibiotic ...

Resistance to nonribosomal peptide antibiotics mediated by d-stereospecific peptidases

open access: yes, 2018
Nonribosomal peptide antibiotics, including polymyxin, vancomycin, and teixobactin, most of which contain d-amino acids, are highly effective against multidrug-resistant bacteria.
