A new class EC 7, Translocases, has been added to the EC list. It will be part of ENZYME from release 2018_10. Read more about EC 7 here.

ENZYME entry: EC

Accepted Name
Glycoprotein 3-alpha-L-fucosyltransferase.
Alternative Name(s)
GDP-fucose:beta-N-acetylglucosamine (Fuc to (Fuc-alpha-1->6-GlcNAc)-Asn- peptide) alpha-1->3-fucosyltransferase.
GDP-L-Fuc:Asn-linked GlcNAc alpha-1,3-fucosyltransferase.
GDP-L-Fuc:N-acetyl-beta-D-glucosaminide alpha-1,3-fucosyltransferase.
Reaction catalysed
GDP-L-fucose + N(4)-(N-acetyl-beta-D-glucosaminyl-(1->2)-alpha-D-mannosyl-(1->3)-(N-acetyl-beta-D-glucosaminyl-(1->2)-alpha-D-mannosyl-(1->6))-beta-D-mannosyl-(1->4)-N-acetyl-beta-D-glucosaminyl-(1->4)-N-acetyl-beta-D-glucosaminyl)asparagine <=> GDP + N(4)-(N-acetyl-beta-D-glucosaminyl-(1->2)-alpha-D-mannosyl-(1->3)-(N-acetyl-beta-D-glucosaminyl-(1->2)-alpha-D-mannosyl-(1->6))-beta-D-mannosyl-(1->4)-N-acetyl-beta-D-glucosaminyl-(1->4)-(alpha-L-fucosyl-(1->3))-N-acetyl-beta-D-glucosaminyl)asparagine
  • The enzyme transfers to N-linked oligosaccharide structures (N-glycans), generally with a specificity for N-glycans with one unsubstituted non-reducing terminal GlcNAc residue.
  • This enzyme catalyzes a reaction similar to that of EC, but transferring the L-fucosyl group from GDP-beta-L-fucose to form an alpha-1,3-linkage rather than an alpha-1,6-linkage.
  • The N-glycan products of this enzyme are present in plants, insects and some other invertebrates (e.g., Schistosoma, Haemonchus, Lymnaea).
