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

• Sulfation of heparan sulfate occurs at C2 of HexA. It also occurs at C3, C6, and NS residues of GlcNAc or GlcNS. HSPGs are major regulators of cell behavior with roles in inflammation, blood coagulation, tumor invasion, and malignancy.
• Seven isoenzymes display HS 3-O-sulfotransferase activity, with all enzymes transferring sulfate to C3 of GlcNAc in heparin and heparan sulfate.
• HS3ST1 sulfates an N-sulfo glucosamine (GlcNS) that has a nonsulfated glucuronic acid (GlcA) or an iduronic acid (IdoA) at the nonreducing end. This modification is necessary for anti-thrombin activity of heparin. HS
• HS3ST-2, 3 (3A and 3B), 4, and 6, all sulfate a GlcNS6S residue that has a 2-O-sulfated iduronic acid (IdoA2S) on the nonreducing end. This does not provide anti-thrombin activity, but serves viral entry for herpes simplex virus type-1.
• The tissue distribution of the different HS3STs is quite different.
