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

• ER resident enzyme.
• Adds GalNAc to create Type I LacdiNAc structures on both N-glycans and O-glycans, but not glycolipid substrates.
• In particular it forms O-Mannosylated structures on α-dystroglycans, and this is necessary for laminin binding. Thus, it is a critical enzyme that is required for normal development of muscle and brain.
• Other enzyme substrates are yet unidentified.
