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

• ST6GALNAC6 synthesizes GD1a, GT1aa, and GQ1ba from GM1b, GD1a, and GT1b, respectively. Thus, this enzyme creates disialyl-Lewis a structure using sialyl-Lc4. It acts on lacto-series and globo-series substrates.
• Ubiquitously expressed in many organs, and associated with cancer. Upregulation of ST6GALNAC6 was reported in all livers of tumor-bearing mice of Engelbreth-Holm Swarm sarcoma.
