IUBMB Enzyme Nomenclature


Accepted name: peptide-O-fucosyltransferase

Reaction: GDP-β-L-fucose + [protein]-(L-serine/L-threonine) = GDP + [protein]-3-O-(α-L-fucosyl)-(L-serine/L-threonine)

Other name(s): GDP-L-fucose:polypeptide fucosyltransferase; GDP-fucose protein O-fucosyltransferase; GDP-fucose:polypeptide fucosyltransferase; POFUT1 (gene name); POFUT2 (gene name)

Systematic name: GDP-β-L-fucose:protein-(L-serine/L-threonine) O-α-L-fucosyltransferase (configuration-inverting)

Comments: The enzyme, found in animals and plants, is involved in the biosynthesis of O-fucosylated proteins. In EGF domains, the attachment of O-linked fucose to serine or threonine occurs within the sequence Cys-Xaa-Xaa-Gly-Gly-Ser/Thr-Cys.
