Widespread protein histidine phosphorylation in bacteria

ABSTRACT: For decades, extreme difficulties in analyzing histidine phosphorylation have limited the study of phosphohistidine signaling. Here we report a method revealing widespread and abundant protein histidine phosphorylation in E. coli. Our new approach generated the largest E. coli phosphoproteome dataset to date, of which a remarkable high percentage (~10%) are phosphohistidine sites. This resource enables a major step forward towards a better understanding of the biological function of histidine phosphorylation.

For decades, major difficulties in analyzing histidine phosphorylation have limited the study of phosphohistidine signaling. Here we report a method revealing widespread and abundant protein histidine phosphorylation in Escherichia coli. We generated an extensive E. coli phosphoproteome data set, in which a remarkably high percentage (∼10%) of phosphorylation sites are phosphohistidine sites. This resource should help enable a better understanding of the biological function of histidine phosphor ...[more]

Multi-omic profiling of primary mouse neutrophils reveals a pattern of sex and age-related functional regulation

Project description:Neutrophils are the most abundant white blood cells in humans and constitute one of the first lines of defense in the innate immune response. Neutrophils are extremely short-lived cells, which survive less than a day after reaching terminal differentiation. Thus, little is known about how organismal aging, rather than the daily cellular aging process, may impact neutrophil biology. In addition, accumulating evidence suggests that both immunity and organismal aging are extremely sex-dimorphic. Here, we describe a multi-omic resource of mouse primary bone marrow neutrophils from young and old female and male animals, at the transcriptomic, metabolomic and lipidomic levels. Importantly, we identify widespread age-related and sex-dimorphic regulation of ‘omics’ in neutrophils, specifically regulation of chromatin metabolism. We leverage machine-learning and identify candidate molecular drivers of age-related and sex-dimorphic transcriptional regulation of neutrophils. We leverage our resource to predict increased levels/release of neutrophil elastase in male mice. To date, this dataset represents the largest multi-omic resource for the study of neutrophils across biological sex and ages. This resource identifies molecular states linked to neutrophil characteristics linked to organismal age or sex, which could be leveraged to improve immune responses across individuals.

Integrated Proteogenomic Characterization of Adenocarcinoma of the esophagogastric junction

Project description:In this study, we performed comprehensive genomic, transcriptomic, proteomic, and phosphorylation analysis of tumor tissues and paired normal adjacent tissues (NATs) of AEG. we describe integrative proteogenomic analyses of the largest cohort to date of AEG samples that focused particularly on novel and clinically actionable insights revealed in the proteome and Phosphorylation modifications. The data may improve current knowledge about AEG and contribute to its diagnosis, prognosis and drug development.

Automated Phosphopeptide Enrichment for Gram Positive Bacteria

Project description:Protein phosphorylation in prokaryotes has gained more attention in recent years as several studies linked it to regulatory and signalling functions indicating an importance similar to protein phosphorylation in eukaryotes. Studies on bacterial phosphorylation have so far been conducted using manual or HPLC-supported phosphopeptide enrichment while automation of phosphopeptide enrichment has been established in eukaryotes, allowing for high throughput sampling. To facilitate the prospect of studying bacterial phosphorylation on a systems‐level we here establish an automated Ser/Thr/Tyr phosphopeptide enrichment workflow on the Agilent AssayMap platform. We present optimized buffer conditions for TiO2 and Fe(III)NTA-IMAC based enrichment, and the most advantageous, species specific starting amount for S. pyogenes, L. monocytogenes, and B. subtilis. Our data represents, to the best of our knowledge, the largest phosphoproteome identified by a single study for each of these bacteria. For higher sample amounts (> 250µg) we observed a superior performance of Fe(III)NTA cartridges, while more peptides were identified from smaller sample amounts using TiO2-based enrichment. Both cartridges largely enrich the same set of phosphopeptides suggesting no improvement of peptide yield from complementary use of both cartridges. Distribution of S/T/Y phosphorylation varied between bacterial strains with threonine being the main site of phosphorylation in S. pyogenes, while in B.subtilis and L. monocytogenes showed the highest percentage of phosphorylation at serine.
