In enzymology a peptide-O-fucosyltransferase (EC 2.4.1.221) is an enzyme that catalyzes the chemical reaction in which an alpha-L-fucosylpyranoside residue is transferred from GDP-beta-L-fucose to the sidechain oxygen atom of a serine or threonine residue in a protein.This enzyme belongs to the family of glycosyltransferases specifically the hexosyltransferases. The systematic name of this enzyme class is GDP-beta-L-fucose:polypeptide O-alpha-L-fucosyltransferase.
