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

• ST3Gal5 (GM3 synthase) acts to create GM3 (starting point for ganglioside synthesis) and also GM4 (on GalCer). In its absence extended gangliosides are not formed. It may also act on GA1.
• In human tissues, expressed at high levels in brain, thymus, lung, spleen, testis, skeletal muscle, thyroid, ovary, and cervix
• ST3Gal5 competes with several enzymes to regulate the pattern of glycolipid biosynthesis. ST3Gal5 (ganglio-series) competes with β1,3-N-acetylglucosaminyltransferase (B3GNT5, lacto, neolacto), α1,3GalT (A3GALT2, isoglobo), α1,4GalT (A4GALT, golobo) and β-1,4-GalNT (B4GALNT1, ganglio) to spatially and developmentally regulated glycosphingolipids.
• GM3 contributes to insulin resistance and metabolic syndrome including type 2 diabetes.
