Fucosyltransferase VII (FucT-VII) is one of five known α1→3fucosyltransferases capable of transferring fucose to the C-3 position ofN-acetylglucosamine residues found in lactosamine based glycans. Previous studies have indicated that FucT-VII has a very restricted specificity, capable of fucosylating only terminally α2→3sialylated carbohydrate substrates, resulting in the synthesis of the sialyl Lewis × (sLex) epitope. Although FucT-VII is expressed in cells of myeloid origin, the monosialylganglioside fraction of HL60 cells contains only internally and/or multiply fucosylated polylactosamine structures; no monofucosylated sLexderivatives are detected. We now report that the structure of the final product formed by the action of FucT-VII on sialynorhexaosylceramide (a glycosphingolipid substrate having multiple fucosylation sites) is extended monofucosyl sLexand fucosylation is restricted to the terminal GlcNAc-V. This indicates that the biosynthesis of all fucosylated monosialylated gangliosides found in HL60 cells (including the E-selectin binding fractions) involves at least one additional α1→3fucosyltransferase.
