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

• Catalyzes 2-O-phosphorylation of xylose during GAG core/protein-linkage structure biosynthesis.
• Xylose 2-O-phosphorylation may influence the catalytic activity of B3GAT3 ('GlcAT-I'). This then impacts HS, CS and DS biosynthesis.
• Cells lacking Fam20B cannot extend the tetrasaccharide linkage and thus have immature and nonfunctional proteoglycan, a phenotype remarkably similar to Ehlers-Danlos syndrome.
