ProteomicsSite-specific N- and O-glycosylation Analysis of Human Plasma Fibronectin
Human plasma fibronectin is an adhesive protein that plays a crucial role in wound healing. Many studies had indicated that glycans may mediate the expression and functions of fibronectin, yet a comprehensive understanding of its glycosylation is still missing. Here, we performed a comprehensive N- ...

ProteomicsMS-based sequencing of the anti-FLAG-M2 antibody
We demonstrate a method for direct de novo sequencing of monoclonal IgG from the purified antibody products. The method uses a panel of multiple complementary proteases to generate suitable peptides for de novo sequencing by LC-MS/MS in a bottom-up fashion. Furthermore, we apply a dual fragmentation...

MetabolomicsIntegrated multi-omics reveals Enterococcus faecalis JM263 alleviates high-concentrate diet-induced hepatic injury via the gut-liver axis in goats

This dataset contains raw liquid chromatography-tandem mass spectrometry (LC-MS/MS) data derived from the liver tissues of goats (Capra hircus). The purpose of this study is to explore the metabolic regulatory mechanism of the probiotic Enterococcus faecalis JM263 in goats fed a high-concentrate ...

ProteomicsLarge scale intact glycopeptide identification by Mascot database search
We present the adaptability of Mascot search engine for automated identification of intact glycopeptide mass spectra. The steps involved in adopting Mascot for intact glycopeptide analysis include: i) assigning unique one letter codes for monosaccharides, ii) linearizing glycan sequences and iii) pr...

ProteomicsEnrichment and Fragmentation Approaches for Enhanced Detection and Characterization of Endogenous Glycosylated Neuropeptides
Glycosylation, a common and heterogeneous post-translational modification plays a key role in altering biomolecule function and other properties. Prior to monitoring regulatory roles, basal glyconeuropeptide expression must be determined. Characterization is partially limited by the lower abundance ...

MetabolomicsFunctional specialization of bacterial cellular and extracellular fractions contributes to polysaccharide degradation

Bacteroides thetaiotaomicron (Bt), a key commensal of the human gut microbiota, exhibits robust capacity to degrade dietary polysaccharides via carbohydrate-active enzymes (CAZymes). However, the exact spatial distribution and the functional coordination of these enzymes remain poor...

ProteomicsOptimal Dissociation Methods Differ for N- and O-glycopeptides
Site-specific characterization of glycosylation requires intact glycopeptide analysis, and recent efforts have focused on how to best interrogate glycopeptides using tandem mass spectrometry (MS/MS). Beam-type collisional activation, i.e., higher-energy collisional dissociation (HCD), has been a val...
