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

• During O-Fuc modification of TSR1 (thrombospondin type 1) repeat, the first step involves the transfer of fuc by Pofut2 to Ser/Thr in this domain. The absence of Pofut2 in mice results in early embryonic lethality with defects in gastrulation. 
• The next step involves the transfers glucose to O-Fuc by a gene encoding the β3-glucosyltransferase, B3GLCT or B3GALTL. Mutations in B3GLCT in humans results in a multifaceted severe developmental disorder known as Peters-plus syndrome.
• Besides O-fuc, and C-mannosylation also occur on TSR1/thrombospondin-1 domains.
