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

• ST8Sia-III transfers sialic acids to Siaα2-3Galβl-4GlcNAc sequences on N-linked oligosaccharides of glycoproteins or α2-3sialylated glycosphingolipids.
• The substrate specificity of ST8Sia-III toward glycolipids is similar to that of ST8Sia-I (GD3 synthase), and both enzymes synthesize GD3 from GM3.
• However, ST8Sia-III (and perhaps ST8Sia-5), but not ST8Sia-I, is thought to synthesize GT3 from GD3.
• The mouse ST8Sia-III gene (st8sia3) was expressed only in the brain and testis.
• Broad specificity for GSLs and proteins
