Substrate
GDP-beta-L-fucose [CPD:C00325];
beta-D-galactosyl-(1->3)-N-acetyl-beta-D-glucosaminyl-R [CPD:C04656]
Product
GDP [CPD:C00035];
alpha-L-fucosyl-(1->2)-beta-D-galactosyl-(1->3)-N-acetyl-beta-D-glucosaminyl-R
Comment
The enzyme acts on a glycoconjugates where R (see reaction) 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. In humans the main enzyme performing this reaction is encoded by the FUT2 gene (also known as the Secretor gene), which is also able to act on type 2 substrates (see EC 2.4.1.344). The enzyme from the bacterium Helicobacter pylori cannot act on type 2 substrates.
