Antifungal peptides in marine invertebrates [PDF]

Invertebrate Survival Journal, 2010
A majority of terrestrial and marine organisms use to fend off a wide range of microorganisms, including bacteria and fungi by employing “antimicrobial peptides (AMPs)” that are ribosomally synthesized from proteinogenic amino acids.

Piecing together nonribosomal peptide synthesis

Current Opinion in Structural Biology, 2018
Nonribosomal peptide synthetases (NRPSs) produce peptide products with wide-ranging biological activities. NRPSs are macromolecular machines with modular assembly-line logic, a complex catalytic cycle, moving parts and multiple active sites. They are organized into repeating sets of domains, called modules.

Dissecting and Exploiting Nonribosomal Peptide Synthetases

Acta Biochimica et Biophysica Sinica, 2004
A large number of therapeutically useful cyclic and linear peptides of bacteria or fungal origin are synthesized via a template-directed, nucleic-acid-independent nonribosomal mechanism. This process is carried out by mega-enzymes called nonribosomal peptide synthetases (NRPSs).

Discovery and Biosynthesis of the Novel Glycotetrapeptide Antibiotic Biffamycin A

Angewandte Chemie, Volume 138, Issue 26, 22 June 2026.
Genetic de‐regulation of a silent biosynthetic pathway allowed isolation and characterisation of a novel glycopeptide antibiotic named biffamycin A, which harbours unprecedented 5‐chloro‐4‐methoxy tryptophan and 3R‐hydroxy(α‐D‐mannoysl)‐D‐lysine moieties and is bioactive against MRSA and VRSA.

The insect pathogen Serratia marcescens Db10 uses a hybrid non-ribosomal peptide synthetase-polyketide synthase to produce the antibiotic althiomycin [PDF]

, 2012
There is a continuing need to discover new bioactive natural products, such as antibiotics, in genetically-amenable micro-organisms. We observed that the enteric insect pathogen, Serratia marcescens Db10, produced a diffusible compound that inhibited the

Identification of a Nonribosomal Peptide Analog With Activity Against Multiple Gram‐Positive Bacteria via a Synthetic Bioinformatic Natural Product Discovery Approach

Advanced Science, EarlyView.
The genome of Rhodococcus erythropolis D‐1 was analyzed by bioinformatic tools to mine a novel nonribosomal peptide synthetase (NRPS) gene cluster. A nonribosomal peptide analog ZURJC5 associated with the NRPS was chemically synthesized. Through structure‐activity relationship studies, ZURJC28 was ultimately obtained and showed antibacterial activity ...

Norine: update of the nonribosomal peptide resource.

Nucleic acids research, 2019
Norine, the unique resource dedicated to nonribosomal peptides (NRPs), is now updated with a new pipeline to automate massive sourcing and enhance annotation. External databases are mined to extract NRPs that are not yet in Norine. To maintain a high data quality, successive filters are applied to automatically validate the NRP annotations and only ...
