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

• ALG7/DPAGT1 initiates the synthesis of 14 sugar Glc3Man9GlcNAc2 on dolichol pyrophosphate. This is a lipid linked oligosaccaride (LLO) where 7 monosaccharides are added in the cytoplasmic side and 7 in the ER lumen.
• ALG7 adds GlcNAc to dolichol phosphate (P-Dol) to generate GlcNAc-PP-Dol.
• Tunicamycin acts as a tight-binding competitive inhibitor of DPAGT1, presumably because it structurally resembles the donor nucleotide sugar.
• Mice lacking DPAGT1 are embyonic lethal in early days following implantation.
• CDG type I are a class of Congenital Disorders of Glycosylation that reduces site occupany of N-glycans. Enzymes causing CDG-I are commonly associated with deficiencies in LLO biosynthesis.
• ALG7/DPAGT1 Mutations in human results in CDG-Ij. It also causes Limb-Girdle congential myasthenic syndrome.
