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

• There are 4 enzymes that perform 3-O-sulfation of Gal.
• Gal3ST1: Acts on GalCer and LacCer to create sulfated glycolipids. Catalyzes the synthesis of sulfatides and seminolpids.
• Gal3ST2: Galβ1,4GlcNAc of O- and N-glycan, can act on sulfated substrates to form bisulfated carbohydrates like 3′,6-disulfo LewisX and 3′,6'-disulfo LewisX. This can also form 3'-sulfo-Le a and 3-O-sulfo-LeX determinants and it can act on lipid substrates
• Gal3ST3 Galβ1,4GlcNAc of O- and N-glycan and Galβ1,4GalNAc of GloboH structure. Can act on sulfated substrates to form bisulfated carbohydrates
• Gal3ST4 Galβ1,4GalNAc of Globo glycolipids and glycopeptides
