Abstract Summary: Glycosylation is one of the most important post-translational modifications proteins, known to be involved in pathogen recognition, innate immune response and protection epithelial membranes. However, when compared tools databases available for processing high-throughput proteomic data, glycomic domain severely lacking. While assist analysis mass spectrometry (MS) HPLC are continuously improving, there few resources support liquid chromatography (LC)–MS/MS techniques glycan...

Recent progress in method development for characterising the branched structures of complex carbohydrates has now enabled higher throughput technology. Automation structure analysis then calls software since adding meaning to large data collections reasonable time requires corresponding bioinformatics methods and tools. Current glycobioinformatics resources do cover information on function glycans, their interaction with proteins or enzymatic synthesis. However, this is partial, scattered...

Abstract Dynamic changes in protein glycosylation impact human health and disease progression. However, current resources that capture phenotype information focus primarily on the macromolecules within central dogma of molecular biology (DNA, RNA, proteins). To gain a better understanding organisms, there is need to functional glycans biological processes. A workshop titled “Functional their curation” was held conjunction with 16th Annual International Biocuration Conference discuss ongoing...

Abstract Motivation: Glycosylation is one of the most important post-translational modifications proteins and explains some aspects diversification higher organisms not explained by template-driven synthesis. For glycomics to mature as much genomics proteomics, necessary tools need be developed tested. Liquid chromatography-mass spectrometry gold standards for oligosaccharide analysis leads large amounts data, easily interpreted manually. We present a study on testing validation statistical...

Collision induced dissociation (CID) fragmentation was compared between reducing and reduced sulfated, sialylated, neutral O-linked oligosaccharides. It found that of the [M - H](-) ions aldoses with acidic residues gave unique Z-fragmentation end GalNAc containing C-6 branch, where entire C-3 branch lost. This pathway, which is not seen in alditols, showed process involved charge remote catalyzed by a anomeric proton. With structures sialic acid on both were dominated loss acid. pathway...

Sulfation is the final decoration of mucin-type O-linked oligosaccharides before mucins are released into lumen gastrointestinal, respiratory, and genital tracts. Because only a fraction undergo this type modifications in Golgi apparatus, sometimes also by dedicated cells, glycobiology these low abundant sulfated often overlooked. At same time, technology to consistently identify characterize them has been lagging. We adopted higher energy collisional dissociation from porcine gastric human...

The level of ambiguity in describing glycan structure has significantly increased with the upsurge large-scale glycomics and glycoproteomics experiments. Consequently, an ontology-based model appears as appropriate solution for navigating these data. However, navigation is not sufficient should also enable advanced search comparison. A new ontology a tree logical introduced to represent structures irrespective precision molecular details. heavily relies on GlycoCT encoding structures. Its...

Abstract Recent technological advances in glycobiology have resulted a large influx of data and the publication many papers describing discoveries glycoscience. However, terms used glycan structural features are not standardized, making it difficult to harmonize across biomolecular databases, hampering harvesting information studies hindering text mining curation efforts.

Although cryptographic and non-cryptographic hash functions are everywhere, there seems to be a gap in how they designed. Lots of criteria exist for hashes motivated by various security requirements, but on the side is certain amount folklore that, despite long history functions, has not been fully explored. While targeting uniform distribution makes lot sense real-world datasets, it can challenge when confronted dataset with particular patterns.
