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

• ST8Sia-I, ST8Sia-III, and ST8Sia-V show broad activities, but distinct specificity, toward most gangliosides. ST8Sia-V shows preference for GD1a and GT1b (KM~70-80 mM), higher for GD3 and highest for GM1b and α2-3sialylparaglobosides. ST8Sia-3 is better for GD3 and α2-3sialylparaglobosides, and ST8Gal-I prefers GM3 (KM=30mM).
• Mainly expressed in the brain and the expression increased with aging.
