The GlycoDomain Viewer is a tool for the visualisation of glycosylation sites in the context of the protein and conserved domains. It contains O-glycoproteomic data from the Clausen lab, and predictions of GalNAc-type glycosylation for the human proteome.
Predict possible oligosaccharide structures that occur on proteins from their experimentally determined masses. The program can be used for free or derivatized oligosaccharides and for glycopeptides.

GlycoSiteAlign selectively aligns amino acid sequences surrounding glycosylation sites (by default, 20 positions on each side of the glycosylated residue) depending on structural properties of the glycan attached to the site. These properties are either general (e.g., "fucosylated") or specific, such as precise composition, and are proposed in a drop-down list.
Visualisation tool for representing a set of glycan structures as a summary figure of all structural features using icons and colours recommended by the Consortium for Functional Glycomics (CFG).
MatrixDB is a curated database of interactions between extracellular matrix proteins, proteoglycans and polysaccharides. It mainly focuses on protein-glycosaminoglycan (GAG) interactions, as GAGs are complex and abundant polysaccharides in the ECM and at the cell surface, where they play key roles in adhesion and signaling.
MzJava is an open-source Java library for the analysis of mass spectrometry data. It provides algorithms and data structures for processing mass spectra and their associated biological molecules, such as small molecules, glycans, proteins, and peptides with post-translational modifications. MzJava includes methods to perform mass calculation, protein digestion, peptide and glycan fragmentation, MS/MS signal processing, and scoring for spectra-spectra and peptide/glycan-spectra matches.
Neural network predictions of C-mannosylation sites in mammalian proteins.
NetNGlyc predicts N-Glycosylation sites in human proteins using artificial neural networks that examine the sequence context of Asn-Xaa-Ser/Thr sequons.
Neural network predictions of mucin type GalNAc O-glycosylation sites in mammalian proteins.
This database provides a list of known carbohydrate sequences to which pathogenic organisms specifically adhere via lectins or adhesins. The data were compiled through an exhaustive search of literature published over the past 30 years by glycobiologists, microbiologists, and medical histologists.
Swiss Mass Abacus is a calculator of peptide and glycopeptide masses. It is purposefully kept as simple as a basic calculator executing arithmetic operations.
UniCarbKB is a curated and annotated glycan database which curates information from the scientific literature on glycoprotein derived glycan structures. It includes data previously available from GlycoSuiteDB.
The YinOYang WWW server produces neural network predictions for O-beta-GlcNAc attachment sites in eukaryotic protein sequences. This server can also use NetPhos, to mark possible phosphorylated sites and hence identify "Yin-Yang" sites.
