GDP-fucose protein O-fucosyltransferase and related proteins. O-fucosyltransferase-like proteins are GDP-fucose dependent enzymes with similarities to the family 1 glycosyltransferases (GT1). They are soluble ER proteins that may be proteolytically cleaved from a membrane-associated preprotein, and are involved in the O-fucosylation of protein substrates, the core fucosylation of growth factor receptors, and other processes.

Alpha 1,6-fucosyltransferase similar to Bradyrhizobium NodZ. Bradyrhizobium NodZ is an alpha 1,6-fucosyltransferase involved in the biosynthesis of the nodulation factor, a lipo-chitooligosaccharide formed by three-to-six beta-1,4-linked N-acetyl-d-glucosamine (GlcNAc) residues and a fatty acid acyl group attached to the nitrogen atom at the non-reducing end. NodZ transfers L-fucose from the GDP-beta-L-fucose donor to the reducing residue of the chitin oligosaccharide backbone, before the attachment of a fatty acid group.

GDP-fucose protein O-fucosyltransferase. This is a family of conserved proteins representing the enzyme responsible for adding O-fucose to EGF (epidermal growth factor-like) repeats. Six highly conserved cysteines are present in O-FucT-1 as well as a DXD-like motif (ERD), conserved in mammals, Drosophila, and C. elegans. Both features are characteristic of several glycosyltransferase families. The enzyme is a membrane-bound protein released by proteolysis and, as for most glycosyltransferases, is strongly activated by manganese.

GDP-fucose protein O-fucosyltransferase 2. O-FucT-2 adds O-fucose to thrombospondin type 1 repeats (TSRs), and appears conserved in bilateria. The O-fucosylation of TSRs appears to play a role in regulating secretion of metalloproteases of the ADAMTS superfamily. O-fucosyltransferase-like proteins are GDP-fucose dependent enzymes with similarities to the family 1 glycosyltransferases (GT1). They are soluble ER proteins that may be proteolytically cleaved from a membrane-associated preprotein, and are involved in the O-fucosylation of protein substrates, the core fucosylation of growth factor receptors, and other processes.
