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

• ppGalNAc-T1 is localized throughout the Golgi
• Mutations in ppGalNAcT activity can result in various diseases
• ppGalNAc-T2 and ppGalNAc-T3 were more abundant in the trans and medial Golgi
• GALNT4 may act better on substrates that already have a single GalNAc, i.e. it may have 'follow-up' characteristics
