N-glycans are highly common sources of nutrition for human colonic-dwelling bacteria. These microbes have evolved a several methods to remove N-glycans from proteins; herein we describe the biochemica...

A new lasso peptide antibiotic exhibits broad-spectrum activity against Gram-negative and Gram-positive bacteria by interfering with bacterial protein synthesis, is unaffected by common resistanc...

Neonatal antibiotic use is shown to reduce immune response to infant vaccines, accompanied by reduced abundance of Bifidobacteria in the gut microbiota, with experiments in mice indicating that probio...

Synthetic peptides, inspired by the natural defenses of amphibians, demonstrate selective activity against Gram-negative pathogens while sparing the gut microbiota and Gram-positive strains. Rationall...

The purpose of the day is to achieve full and equal access to and participation in science for women and girls.

Antibiotika sollen möglichst toxisch für krankmachende Bakterien sein und gleichzeitig harmlos für die Zellen des menschlichen Körpers. Das HIPS hat nun Wirkstoffkandidaten entwickelt, denen genau das...

A combined strategy of 2D-NMR-metabolomics-driven substructure tracking with genome mining led to the targeted discovery of 10 nocobactin-type lipopeptides (1–10) from the Arctic-derived phychrophillic Nocardia sp. L-016, among which 1–5 are new compounds, named nocardimicins S–W. The phenoxazole moiety in 1–10, featuring unique NMR values and correlations, was used as a probe for tracking nocardimicin analogues. The structures of 1–5 were established based on extensive MS and NMR spectroscopic analyses. The biosynthesis of nocardimicins (1–10) in Nocardia sp. L-016 is proposed to be achieved by the noc biosynthetic gene cluster, which is composed of two sub-gene clusters (I and II) separated by a 228 kb region. Compounds 1–10 showed moderate inhibition against human cancer cell lines of HCT116 and HepG2 with IC50 values in the range of 3.5–10.2 μM. This work provides an effective application of paired-omics technologies in the discovery of new natural products.

Microbiology research has historically focused on a few species of model organisms. Our bibliographic analysis finds extreme bias in the distribution of bacteriology research across species, with half...
