[https://www.uniprot.org/uniprot/FUT9_HUMAN FUT9_HUMAN] Catalyzes the transfer of L-fucose, from a guanosine diphosphate-beta-L-fucose, to the N-acetyl glucosamine (GlcNAc) of a distal lactosamine unit of a glycoprotein or a glycolipid-linked polylactosamine chains through an alpha-1,3 glycosidic linkage and participates in particular to the Lewis x (Lex)/CD15 epitope biosynthesis in neurons which allows cell differentiation, cell adhesion, and initiation of neurite outgrowth (PubMed:23263199, PubMed:23192350, PubMed:10386598, PubMed:17335083, PubMed:23000574, PubMed:11278338, PubMed:10622713, PubMed:18395013, PubMed:12107078, PubMed:16282604, PubMed:29593094). Also fucosylates di-, tri- and tetraantennary N-glycans linked to glycoproteins and the inner lactosamine unit of the alpha2,3-sialylated polylactosamine resulting in sLex (CD15s) epitope synthesis (PubMed:12107078, PubMed:18395013). Furthermore, it is capable of synthesizing Lewis a (Lea), although to a lesser extent than Lex and Lewis y (Ley) and to confer SELE-dependent, but not SELL- and SELP-selectin-dependent, cell rolling and adhesion by enhancing Lex and sLex synthesis (PubMed:18395013, PubMed:23192350). May also fucosylate the internal LacNAc unit of the polylactosamine chain to form VIM-2 antigen that serves as recognition epitope for SELE.<ref>PMID:10386598</ref> <ref>PMID:10622713</ref> <ref>PMID:11278338</ref> <ref>PMID:12107078</ref> <ref>PMID:16282604</ref> <ref>PMID:17335083</ref> <ref>PMID:18395013</ref> <ref>PMID:23000574</ref> <ref>PMID:23192350</ref> <ref>PMID:23263199</ref>

== Publication Abstract from PubMed ==
 +
Mammalian cell surface and secreted glycoproteins exhibit remarkable glycan structural diversity that contributes to numerous physiological and pathogenic interactions. Terminal glycan structures include Lewis antigens synthesized by a collection of alpha1,3/4-fucosyltransferases (CAZy GT10 family). At present, the only available crystallographic structure of a GT10 member is that of the Helicobacter pylori alpha1,3-fucosyltransferase, but mammalian GT10 fucosyltransferases are distinct in sequence and substrate specificity compared with the bacterial enzyme. Here, we determined crystal structures of human FUT9, an alpha1,3-fucosyltransferase that generates Lewis(x) and Lewis(y) antigens, in complex with GDP, acceptor glycans, and as a FUT9-donor analog-acceptor Michaelis complex. The structures reveal substrate specificity determinants and allow prediction of a catalytic model supported by kinetic analyses of numerous active site mutants. Comparisons with other GT10 fucosyltransferases and GT-B fold glycosyltransferases provide evidence for modular evolution of donor- and acceptor-binding sites and specificity for Lewis antigen synthesis among mammalian GT10 fucosyltransferases.
