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 exo-sialidase cleavage of sialic acid on various glycolipids, glycoproteins and oligosacharides.
• Shown to function on α2,3 sialic acid of GD1a & GM3, and α2,8 sialic acid of GD3.
• May also have roles in signaling and regulating endocytosis.
• During N-glycan degradation, oligosaccharides sialidase removal typically precedes activity of α- and β-Galactosidase, β-N-Acetylhexosaminidases, and α-Mannosidases. Manβ1-4GlcNAc is cleaved by β-Mannosidase in the last step.
