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 the transfer of galactose from UDP-galactose to ganglioside GM2 to form GM1. Also forms GD1b and GA1 (asialo-GM1) from GD2, and asialo-GM2, respectively.
• B3GALT4 is expressed at high levels in the nervous tissues, while it was widely expressed in various organs and cells.
• This enzyme can also catalyze the side arm of GPI-anchored proteins
