The effect of gougerotin analogues on ribosomal peptidyl transferase

FEBS Letters, 1971
1. Introduction Gougerotin (I), a dipeptidyl pyrimidine nucleoside antibiotic, has been found to specifically inhibit the step of protein biosynthesis which is catalyzed by ribosomal peptidyl transferase [l-S] . Since three gougerotin analogues have been synthesized recently [6] , 1-[3(sarcosyl-D-seryl-)amino3-deoxy$-D-gluco- pyranosyl-)uracil (II, cf.

Ribozymes for RNA‐Catalyzed RNA Methylation and Labeling

Angewandte Chemie International Edition, EarlyView.
Ribozymes are powerful tools for site‐specific RNA modification. Their activities range from installing tags and fluorophores to generating natural RNA methylations, making them valuable tools to uncover the many functions that RNA plays in nature.

The Quality Control of Midecamycin and the Predictive Demarcation between Its Impurities and Components

Separations, 2022
Midecamycin is a 16-membered macrolide antibiotic. It can inhibit the synthesis of bacterial proteins by blocking up the activity of peptidyl transferase in the 50S ribosome.

Bacterial riboproteogenomics : the era of N-terminal proteoform existence revealed [PDF]

, 2020
With the rapid increase in the number of sequenced prokaryotic genomes, relying on automated gene annotation became a necessity. Multiple lines of evidence, however, suggest that current bacterial genome annotations may contain inconsistencies and are ...

Exercise‐specific plasma proteomic signatures in racehorses: Candidates for training adaptation and peak load monitoring

Equine Veterinary Journal, EarlyView.
Abstract Background Racehorses undergo profound physiological changes with training and competition, but current biomarkers inadequately capture the complex molecular dynamics of exercise. This study aimed to identify novel plasma biomarkers of training adaptation and peak load using high‐throughput proteomics.

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

SPROUTS_DB: An Implemented Database of Contaminants for Extracellular Vesicle Proteomics Studies

PROTEOMICS, EarlyView.
ABSTRACT Current proteomics techniques allow rapid identification and quantification of proteins within any given biological source. However, LC–MS/MS proteomics is vulnerable to laboratory and sample‐associated contaminants. Therefore, accurate identification and annotation of such contaminants is crucial for development of reliable databases ...
