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

• Involved in the formation of NeuAc(α2,6)Gal linkages on TypeII lactosamine chains of N-linked glycans
• Ubiquitous enzyme with high expression in liver, lactating mammary gland, hematopoietic activated B cells, and subset of T cells
• ST6Gal I prefers a galactose residue at the α1,3-Man arm of N-linked glycans for addition of the first sialic acid residue.
• SNA and TJA-I bind (α2,6)Sia
• Mice lacking ST6Gal-I display impaired B cell activation and humoral immunity. This may be due to the impairment of Siglec binding, particularly CD22.
• Avian influenza virus HA preferentially recognizes α2,3-sialylated glycans, while human influenza virus HA prefers α2,6-sialylated glycans.
