The tryptophan prenyltransferase ComQ from Bacillus subtilis 168 can prenylate daptomycin at Trp1

The FEBS Journal, EarlyView.
ComQ168 from Bacillus subtilis 168 catalyzes C‐terminal tryptophan farnesylation of ComX to generate a competence‐inducing pheromone. Recombinant ComQ168 also modifies cyclic peptides, including Daptomycin, likely at the N‐terminal tryptophan. Structural modeling highlights a C‐terminal binding region, supporting substrate promiscuity and establishing ...

Flexing and Stretching in Nonribosomal Peptide Synthetases

Chemistry & Biology, 2012
Re-engineering of nonribosomal peptide synthetase molecular assembly lines has been hampered by a lack of detailed knowledge concerning inter-domain substrate transfer. Recent structural studies of catalytically relevant domain-domain interactions provide valuable insights into this problem (Liu et al., 2011; Sundlov et al., 2012 [in this issue of ...

Evolutionary Conserved and Divergent Responses to Copper Zinc Superoxide Dismutase Inhibition in Plants

Plant, Cell &Environment, EarlyView.
ABSTRACT After an initial evolution in a reducing environment, life got successively challenged by reactive oxygen species (ROS), especially during the great oxidation event (GOE) that followed the development of photosynthesis. Therefore, ROS are deeply intertwined into the physiological, morphological and transcriptional responses of most present‐day

Delftibactin-A, a Non-ribosomal Peptide With Broad Antimicrobial Activity

Frontiers in Microbiology, 2019
The rapid emergence of drug resistant bacteria is occurring worldwide, outpacing the development of new antibiotics. It is known that some of the main sources of antibiotics are the bacteria themselves, many of which are secondary metabolites of Gram ...

Actinomycin Derivatives: Structural Diversification and Biological Activities

ChemMedChem, Volume 21, Issue 15, 14 August 2026.
Actinomycins are chromopeptide antibiotics exhibiting remarkable structural diversity and broad bioactivity. This review traces their development from naturally occurring D‐, X‐, A‐, G‐, Y‐, and Z‐type analogs to precursor‐directed, synthetic, and semisynthetic derivatives.

Improved Incorporation of Arylglycines Into Ramoplanin Sequences via Solid‐Phase Peptide Synthesis

European Journal of Organic Chemistry, Volume 29, Issue 30, 12 August 2026.
The incorporation of arylglycines using solid‐phase peptide synthesis remains challenging due to the sensitivity of these residues for epimerization. Here, exploring multiple conditions for the incorporation of arylglycine residues into peptides using SPPS demonstrates how small changes to current synthesis protocols can lead to significant ...

Streptavidins Coordinate Biotin Sequestration and Self‐Resistance Within a Biotin‐Pathway Antibiotic Network

Advanced Science, Volume 13, Issue 46, 17 August 2026.
A conserved genomic region between two streptavidin genes in Streptomyces packages biosynthetic gene clusters for diverse biotin‐pathway antibiotics: acidomycin, stravidin, the new non‐proteinogenic amino acid ANDA, and the new BioA inhibitor α‐methyl‐KAPA.

Structural basis of nonribosomal peptide macrocyclization in fungi [PDF]

Nature Chemical Biology, 2016
Nonribosomal peptide synthetases (NRPSs) in fungi biosynthesize important pharmaceutical compounds, including penicillin, cyclosporine and echinocandin. To understand the fungal strategy of forging the macrocyclic peptide linkage, we determined the crystal structures of the terminal condensation-like (CT) domain and the holo thiolation (T)-CT complex ...

Microbial Oxidative Stress in Food Fermentations: A Comprehensive Review

eFood, Volume 7, Issue 4, August 2026.
Oxidative stress has a dual role in food fermentations: low ROS supports adaptive signaling, whereas excessive ROS causes cellular damage and process inhibition. Managing redox state as a controllable process variable can improve fermentation robustness and final food quality.
