IUBMB Enzyme Nomenclature


Accepted name: peptide-O-fucosyltransferase

Reaction: transfers an α-L-fucosyl residue from GDP-β-L-fucose to the serine hydroxy group of a protein acceptor

Other name(s): GDP-L-fucose:polypeptide fucosyltransferase; GDP-fucose protein O-fucosyltransferase; GDP-fucose:polypeptide fucosyltransferase

Systematic name: GDP-β-L-fucose:polypeptide O-α-L-fucosyltransferase

Comments: Involved in the biosynthesis of O-fucosylated epidermal growth factor (EGF) and thrombospondin type 1 repeats. The attachment of O-linked fucose to serine or threonine occurs on EGF domains within the sequence Cys-Xaa-Xaa-Gly-Gly-Ser/Thr-Cys.
