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

• Forms type 1 LacNAc chains (Galβ1-3GlcNAc) primarily in cell types derived from the endoderm (lung, thyroid, pancreas etc.).
• Helps form Lewisa and Lewisb antigens, and also sialyl-Lea (CA19-9) and disialyl-Lea (FH7).
• Three enzymes may form the type I LacNAc chain (B3GalT-1, -2 and -5). The expression pattern of these three enzymes vary with B3Gal-T1 being restricted to brain as well as intestine and colon; B3Gal-T2 in heart, brain, and bone marrow; and B3Gal-T5 in the gastrointestinal tract.
• B3Gal-T1 showed activity toward simple βGlcNAc saccharides and lactoseries glycosphingolipids, but not N-glycans on ovalbumin and asialo-agalacto-fetuin.
• B3Gal-T2 shows activity with both simple βGlcNAc saccharides, βGlcNAc terminating lactoseries glycosphingolipids, and ovalbumin and asialoagalacto-fetuin N-glycoprotein acceptors.
• B3Gal-T5 produces type 1 chain linkage in glycolipids and core-3 O-glycans, but not N-linked glycoproteins.
• Thus, multiple enzymes act on GSLs, but only B3GalT2 is the primary enzyme modifying N-glycans.
