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

• ST3Gal-III prefers Galβ1-3GlcNAc, but also acts on Galβ1-4GlcNAc (Km < 0.1 mM) and Galβ1-3GalNAc (Km=4 mM) termini on glycoproteins, oligosaccharides and glycolipids.
• Evidence suggests that the enzyme may prefer the gangliotetraose terminus (Galβ1-3GalNAcβ1-4Gal) compared to core 1 O-linked glycans (Galβ1-3GalNAcα1-Ser/Thr).
• Mutations in the ST3GAL3 gene in humans are associated with rare severe familial intellectual disability
• ST3GAL3 gene is widely expressed in human tissues, with higher mRNA levels in the brain, skeletal muscle, adrenal gland, uterus, and lymphocytes.
• Likely to play a role in regulating Siglec function.
