Numerous vertebrates have four alpha-1,3/4-fucosyltransferase genes (FUT9, FUT7, FUT4, and FUT Lewis) belonging to the same family. Until now, studies on the evolution of this family have mainly focused on Lewis genes but how the other alpha-1,3/4-fu

Structure/function study of Lewis 3- and 3/4-fucosyltransferases: the 1,4 fucosylation requires an aromatic residue in the acceptor-binding domain

Autor: Abderrahman Maftah, Fabrice Dupuy, Agnès Germot, Raymond Julien

Publikováno v: Glycobiology. 14:347-356

All vertebrate alpha3- and alpha3/4-FUTs possess the characteristic acceptor-binding motif VxxHH(W/R)(D/E). FUT6 and FUTb enzymes, harboring R in the acceptor-binding motif, transfer fucose in alpha1,3 linkage, whereas FUT3 and FUT5 enzymes with W at

The fucosyltransferase gene family encodes enzymes that transfer fucose in α1,2, α1,3/4 and α1,6 linkages on a large variety of glycans. The most ancient genes harbour a split coding sequence, and encode enzyme that transfer fucose at or near O- a

Ancestral Exonic Organization of FUT8, the Gene Encoding the α6-Fucosyltransferase, Reveals Successive Peptide Domains Which Suggest a Particular Three-Dimensional Core Structure for the α6-Fucosyltransferase Family

Publikováno v: Molecular Biology and Evolution. 17:1661-1672

Based on PCR strategies and expression studies, we define the genomic organization of the FUT8b gene. This gene encodes the only known mammalian enzyme transferring fucose in an alpha1-->6 linkage on the asparagine-branched GlcNAc residue of the chit

Human α1,3 fucosyltransferases (FucTs) contain four highly conserved cysteine (Cys) residues, in addition to a free Cys residue that lies near the binding site for GDP-fucose (Holmes, E. H., Xu, Z., Sherwood, A. L., and Macher, B. A. (1995)J. Biol.

Three bovine 2-fucosyltransferase genes encode enzymes that preferentially transfer fucose on Gal 1-3GalNAc acceptor substrates

Publikováno v: Glycobiology. 10:611-621

To investigate the synthesis of alpha2-fucosylated epitopes in the bovine species, we have characterized cDNAs from various tissues. We found three distinct alpha2-fucosyltransferase genes, named bovine fut1, fut2, and sec1 which are homologous to hu

A Single Amino Acid in the Hypervariable Stem Domain of Vertebrate α1,3/1,4-Fucosyltransferases Determines the Type 1/Type 2 Transfer

Publikováno v: Journal of Biological Chemistry. 274:12257-12262

Alignment of 15 vertebrate α1,3-fucosyltransferases revealed one arginine conserved in all the enzymes employing exclusively type 2 acceptor substrates. At the equivalent position, a tryptophan was found in FUT3-encoded Lewis α1,3/1,4-fucosyltransf
