Abstract

We report a straightforward enzymatic synthesis of the 4-methylumbelliferyl glycoside of a complex-type oligosaccharide substrate for core fucosylation. We demonstrate the use of this synthetic glycoconjugate in a newly developed enzyme assay to probe the activity and inhibition of fucosyltransferase VIII, which catalyzes the core fucosylation of N-glycans on eukaryotic glycoproteins. In this fucosyltransferase assay, we use the fluorogenic probe and a specific glycosidase in a sequentially coupled enzyme reaction to distinguish an unmodified 4-methylumbelliferyl oligosaccharide probe from a fucosylated probe. Our findings show that this strategy is very sensitive and specific in its detection of enzyme activity and can even be used for analyzing impure tissue lysate samples.
