Protein details/Glycosylation
The glycosylation section of the Protein information page in GlyGen provides the detailed list of glycosylation sites, reported glycans attached to the protein and predicted sites.
Glycosylation

Glycosylation is presented in 4 tabs on the Protein information page in GlyGen. The Glycosylation summary provides the overall information about the section like the total number of sites (O,N,S,C linked sites), total number of N linked and O-linked sites with the total number of glycan annotations (structures) observed on the protein. Eg. 18 site(s) total, 169 N-linked annotation(s) at 17 site(s), 1 O-linked annotation(s) at 1 site(s)
Reported Sites with Glycan

This tab shows a table with the following columns:
- Source - GlyGen evidence linking to the databases and papers that provided the glycosylation information
- Type - Type of glycosylation. Eg. N-linked, O-linked
- GlyTouCan ID - Unique accession assigned to the registered glycan structure in GlyTouCan database. Eg. G01543ZX
- Glycan Image - Image of the glycan in SNFG format
- Residue - Amino acid residue of the given protein along with its position.
- Note - Additional information about the entry such as curation notes, O-glycosylation subtype, remarks, etc.

The Glycosylation data is collected and integrated from the resources such as UniProtKB, Glyconnect, UniCarbKB, RCSB PDB, The O-GlcNAc Database.
- UniProtKB - only reported sites information and predicted information is downloaded from UniProtKB
- Glyconnect - reported sites with glycan information on known and unknown residues is downloaded from Glyconnect
- UniCarbKB - reported sites with glycan information on known and unknown residues is downloaded from UniCarbKB
- RCSB PDB - only reported sites information is downloaded from RCSB PDB
- The O-GlcNAc Database - Only O-GlcNAcylation reported sites with glycan information on known and unknown residues is downloaded from The O-GlcNAc database
