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

CAZy Family:   
GT25
E.C. No:   
2.4.1.50

No specified reaction.
About

• Widely expressed (α1-2)GalT that modifies 5-hydroxy-L-lysyl- on collagen and collagen-like domains
• This is an ER resident enzyme involved in the biosynthesis of collagen type IV
• Glycosylation occurs before the formation of the collagen triple helix
• Compared to COLGALT1, COLGALT2 is only expressed at lower levels in the nervous system
• The product of COLGALT1/2 is modified by glucose, though the enzyme mediating this feature is yet unknown
