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

• Keratan sulfate (KS) is composed of repeating disaccharide LacNAc units (Galβ1-4GlcNAc) with C6 sulfation of both Gal and GlcNAc. GlcNAc sulfation often exceeds Gal sulfation suggesting that GlcNAc sulfation may occur first.
• CHST1 has C6 Gal sulfation properties (both for unsulfated LacNAc substrate and also sulfated KS).
• In addition to KS, this enzyme may also contribute to the formation of glycoproteins bearing C6-Gal sulfated sialyl N-acetyllactosamine or sulfated Sialyl-Lewis X oligosaccharides. These glycan structures can act as selectin ligands during lymphocyte homing to HEV (high endothelial venules).
• The enzyme does not act on CS, DS or HS.
• In vitro synthesis of KS has been achieved by mixing some of these sulfotransferases with B4GalT1,4, along with B3GNT2 and 7 (for lactosamine chain extension).
