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

• Extension of Man5GlcNAc2-P-P-Dol in the ER lumen involves the addition of four Man (by ALG3 [α(1,3)ManT], ALG9 [α(1,2)ManT], ALG12 [α(1,6)ManT] followed by ALG9 [α(1,2)ManT] again) and three Glc residues (by ALG6 [α(1,3)GlcT], ALG8 [α(1,3)GlcT] and ALG10 [α(1,2)GlcT]).
• In all instances the transfer uses either Dol-P-Man or Dol-P-Glc as donor.
• Dol-P-Man is formed from GDP-Man using enzymes DPM1,2,3
• Dol-P-Glc is formed from UDP-Glc using ALG5
• Alg 3 is the first enzyme that acts on the lumen-oriented LLO. It adds α1,3-linked mannose to the α1,6 mannose arm. The enzyme uses dolichylphosphomannose (Dol-P-Man) as a donor and Man5GlcNAc2-PP-Dol as an acceptor substrate
• Mutations in Alg 3 results in CDG-Id
