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.

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 Biology of Nonribosomal Peptide Synthetases [PDF]

open access: yes, 2016
The nonribosomal peptide synthetases are modular enzymes that catalyze synthesis of important peptide products from a variety of standard and non-proteinogenic amino acid substrates. Within a single module are multiple catalytic domains that are responsible for incorporation of a single residue. After the amino acid is activated and covalently attached

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 ...

A Fungal Nonribosomal Peptide Synthetase Module that can Synthesize Thiopyrazines

open access: yes, 2016
A nonribosomal peptide synthetase-like enzyme (NRPS325) from Aspergillus terreus was reconstituted in vitro and was shown to synthesize thiopyrazines using an unprecedented mechanism. Substrate promiscuity of NRPS325 toward different amino acids and free

Broad‐Spectrum, Cell Envelope‐Active Marinocyclin Antibiotics From a Coral‐Derived Bacterium Are Effective Against Colistin‐Resistant Bacteria

open access: yesAngewandte Chemie, Volume 138, Issue 43, 19 October 2026.
Marinocyclins, polycationic macrocyclic depsipeptides, were discovered by genome mining from the marine coral‐derived bacterium Aquimarina megaterium. The compounds have broad‐spectrum activity against gram‐positive and gram‐negative ESKAPE bacteria.

Engineering Fungal Nonribosomal Peptide Synthetase-like Enzymes by Heterologous Expression and Domain Swapping

open access: yes, 2016
A facile genetic methodology in the filamentous fungus Aspergillus nidulans allowed the exchange of various domains in nonribosomal peptide synthase (NRPS)-like enzymes from Aspergillus terreus.

ANTIBACTERIAL ACTIVITY OF A SECONDARY METABOLITE-PRODUCING CORAL BACTERIUM Pseudoalteromonas SPECIES [PDF]

open access: yes, 2004
A bacterium, collected at the surface of coral Acropora sp., TAB4.2 was successfully screened for secondary metabolites production based on PCR amplification of the non-ribosomal peptide synthetase gene.
