FunFam 430: Bifunctional glycosyltransferase pgtA

There are 1 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Type 1 galactoside alpha-(1,2)-fucosyltransferase. [EC: 2.4.1.69]
GDP-beta-L-fucose + beta-D-galactosyl-(1->3)-N-acetyl-beta-D- glucosaminyl-R = GDP + alpha-L-fucosyl-(1->2)-beta-D-galactosyl-(1->3)-N- acetyl-beta-D-glucosaminyl-R.
  • The enzyme acts on a glycoconjugates where the substituent group is a glycoprotein or glycosphingolipid.
  • The recognized moiety of the substrate is known as a type 1 histo- blood group antigen precursor disaccharide, and the action of the enzyme produces an H type 1 antigen.
  • The enzyme from the bacterium Helicobacter pylori cannot act on type 2 substrates (see EC 2.4.1.344).
  • Formerly EC 2.4.1.89.
