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

• Cleavage of four α1,2-mannose (α1,2-Man) residues from Man9GlcNAc2-Asn.
• ER resident Man1B1 first cleaves the single α1,2Man residue from the B branch of the Man9GlcNAc2-Asn.
• This intermediate is then rapidly cleaved in the Golgi by the concerted action of Golgi resident α-mannosidases IA, IB, and IC depending on the relative expression levels in specific cell types.
• Cleavage of Man by these enzymes is followed by the addition of GlcNAc by MGAT1.
