Nonribosomal biosynthesis of backbone-modified peptides
Nature Chemistry, 2017Biosynthetic modification of nonribosomal peptide backbones represents a potentially powerful strategy to modulate the structure and properties of an important class of therapeutics. Using a high-throughput assay for catalytic activity, we show here that an L-Phe-specific module of an archetypal nonribosomal peptide synthetase can be reprogrammed to ...

Combinatorial biosynthesis of polyketides and nonribosomal peptides
Current Opinion in Chemical Biology, 2001The engineering of polyketide biosynthesis has begun to provide robust targeted libraries for screening against pharmaceutically relevant targets. New technologies that offer methodology for the rapid generation of more structurally diverse libraries have now been demonstrated.

A Practical Guideline to Engineering Nonribosomal Peptide Synthetases
2023The bioengineering of nonribosomal peptide synthetases (NRPSs) is a rapidly developing field to access natural product derivatives and new-to-nature natural products like scaffolds with changed or improved properties. However, the rational (re-)design of these often gigantic assembly-line proteins is by no means trivial and needs in-depth insights into

FRET monitoring of a nonribosomal peptide synthetase
Nature Chemical Biology, 2017Nonribosomal peptide synthetases (NRPSs) are multidomain enzyme templates for the synthesis of bioactive peptides. Large-scale conformational changes during peptide assembly are obvious from crystal structures, yet their dynamics and coupling to catalysis are poorly understood.

Pseudoaeruginosins, Nonribosomal Peptides in Nodularia spumigena
ACS Chemical Biology, 2014Nodularia spumigena is a filamentous cyanobacterium that forms toxic blooms in brackish waters around the world through the production of the pentapeptide toxin nodularin. This cyanobacterium also produces large amounts of protease inhibitors belonging to the aeruginosin and spumigin families. Here we report the discovery of previously unknown protease

Metagenome Driven Discovery of Nonribosomal Peptides
ACS Chemical Biology, 2019Declining rates of novel natural product discovery and exponential rates of rediscovery heralded the end of the 1940s to 1960s "golden era" of antibiotic discovery. Fifty years later, the implementation of molecular screening methodologies revealed that standard culture-based screening approaches had failed to capture the vast majority of environmental

De Novo Sequencing of Nonribosomal Peptides
2008While nonribosomal peptides (NRPs) are of tremendous pharmacological importance, there is currently no technology capable of high-throughput sequencing of NRPs. Difficulties in sequencing NRPs slow down the progress in elucidating the non-ribosomal genetic code and negatively affect various screening programs aimed at the discovery of natural compounds

Structural Studies of Modular Nonribosomal Peptide Synthetases
2023The non-ribosomal peptide synthetases (NRPSs) are a family of modular enzymes involved in the production of peptide natural products. Not restricted by the constraints of ribosomal peptide and protein production, the NRPSs are able to incorporate unusual amino acids and other suitable building blocks into the final product.

Biosynthetic engineering of nonribosomal peptide synthetases
Journal of Peptide Science, 2016From the evolutionary melting pot of natural product synthetase genes, microorganisms elicit antibiotics, communication tools, and iron scavengers. Chemical biologists manipulate these genes to recreate similarly diverse and potent biological activities not on evolutionary time scales but within months. Enzyme engineering has progressed considerably in
