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

• This is the core 1 extension β1,3GnT enzyme. A Golgi localized Type-2 GlycoT.
• Core-1 extension is possible even after core-2 branching.
• The enzyme exhibits no activity for Type 2 and Type 1 LacNAc chains, thus it is O-glycan specific.
• 6-sulfo extended core-1 structure formed by this enzyme along with the sufotransferase GlcNAc6ST-2/CHST4. This extended epitope is called the 'MECA-79 epitope' which is commonly expressed on HEV and secondary lymphoid organs.
• MECA-79 binds lymphocyte L-selectin, and is thus critical for lymphocyte homing.
• Additionally, the enzyme can support the formation of 6'sulfo sLeX type glycans on the core-1 chain.
• Other organs expressing this enzyme include the mucin producing tissue: small and large intestines, stomach, esophagus, trachea and bladder.
