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

• ER resident protein-O-fucosyltransferases [POFUT1/FUT12 and POFUT2/FUT13] that attach alpha-Fuc to hydroxyl of Ser/Thr at specific consensus sequences of epidermal growth factor (EGF)-like repeats (added by POFUT1) and thrombospondin type 1 repeat (TSR, added by POFUT2).
• Putative consensus sequences for O-fucosylation in EGF repeats [C2-X-X-X-X-(S/T)-C3] and TSRs [C2-X-X-(S/T)-C3-X-X-G] have been defined, where Cx refers to the position of one of the conserved cysteines within the domain and S/T is the site of modification.
• Thus, these enzymes may fucosylate ~100 EGF repeat structures (by POFUT1) and ~30 TSRs (by POFUT2). EGF repeats of proteins bearing O-Fuc include tissue-type plasminogen activator, Factor VII, Factor IX, Notch, Delta, Serrate, Jagged, and Cripto. Examples of TSR1 modified proteins include members of the disintegrin and metalloprotease domain with thrombospondin type 1 repeats family (e.g., ADAMTS 5 and 13) and ADAMTS-like family (e.g., ADAMTSL1; Wang et al. 2007).
• Mice lacking POFUT1 are embryonically lethal, and those without POFUT2 die at E7.5. Thus, both POFUT1 and POFUT2 play essential roles in development.
• POFUT1 plays a key role in regulating Notch dependent signaling.
• The O-fucose on Notch EGF repeats are extended by the Fringe family of β3-GlcNAcTs. They can be further extended to create Siaα2-3/6Galβ1-4GlcNAcβ1-3Fucα-O-Ser/Thr.
• O-Fucose on TSRs is typically found extended to the disaccharide Glcβ1-3Fucα-O-Ser/Thr This extension elongation is due to a β3-glucosyltransferase. Mutations in the β3-glucosyltransferase result in the human developmental disorder Peters plus syndrome. Both O-fucosylated and C-mannosylation occur on TSR1/thrombospondin-1.
