GlycoEnzDB
Comprehensive glycoEnzyme database and dynamic pathway generation

Description: The GlycoEnzDB is a manually curated glycoEnzyme database, primarily focused on humans. It covers 390 enzymes across 28 pathway maps. Facilities are also available to create custom glycosylation reaction pathways using experimental data in SBML format and for pathway simulation

About

• 2-5% of cellular Glc is converted to UDP-GlcNAc. O-GlcNAc transferase (OGT) transfers this GlcNAc to a variety of substrates that regulate cell cycle progression, transcription, intracellular signaling, nutrient sensing, and neuronal plasticity. Such transfer typically takes place in protein regions that are non-structured.
• Due to its broad siubstrate specificity, this enzyme activity is associated with diabetes, neurodegenerative and oncology related disorders.
• The extent of O-GlcNAcylation is regulated by OGT and also an O-GlcNAc hydrolase (OGA), with the latter removing the GlcNAc residue.
• OGT is broadly distributed (particulalry in brain and pancrea) and it exists in three alternate spliced forms.
