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

• Key enzyme for the biosynthesis of b-series gangliosides on glycolipids, thus called GD3 synthase. ST8Sia-I uses GM3 (Neu5Acα2-3Galβ1-4Glcβ1-O-Cer) to form GD3 (Neu5Acα2-8Neu5Acα2-3Galβ1-4Glcβ1-O-Cer) (b-series). This can then form GT3 (c-series gangliosides). ST8Sia I and b- and c-series gangliosides are implicated in oncogenesis by mediating cell proliferation, migration, tumor growth, and angiogenesis. GD3 is weakly expressed in most normal cells but upregulated in cancer.
• Expressed in various organs, particularly the brain, and overexpressed in neuroectoderm-derived malignant cells such as melanoma, glioblastoma, neuroblastoma, and estrogen receptor-negative breast cancer.
• ST8SIA1 knockout mice completely lack b- and c-series gangliosides. However, they show almost complete nervous tissue morphology and no apparent abnormal behavior. But they show reduced reneration of nerve, suggesting a role for the enzyme in repair rather than normal differentiation.
• ST8SIA1 displayed higher expression among ER-negative breast cancer tumors and this is assocaiated with poor pathohistological grading.
