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 3 Synthase, C3GNT, that produces GlcNAc(β1-3)GalNAc(a)-Ser/Thr type O-glycans.
• This can be further extended to form polyLacNac (Gal(β1-4)GlcNAc) on extended Core-3, and also Core-4 structures.
• The enzyme is normally expressed in colon, small intestine and stomach; and it a major modification on normal cells.
• The expression of B3GNT6 gene is downregulated in gastric and colorectal carcinomas, where the O-glycans transition from core-3 to core-1 and core 2 type structures.
• B3gnt6-/- mice are susceptible to experimental triggers of colitis and colorectal adenocarcinoma, suggesting a biological role for the enzyme in the gut.
