An enzymatic method of analysis for GDP-L-fucose in biological samples, involving high-performance liquid chromatography.

To investigate the biological significance of GDP-L-fucose, we established a unique method for the determination of GDP-L-fucose levels in microsomal fractions, using an HPLC assay of alpha 1-6-fucosyltransferase (alpha1-6-FucT), an enzyme that catalyzes the synthesis of core fucosylation in N-glycans. A microsomal protein and a large excess of fluorescence-labeled synthetic oligosaccharide (a substrate) were incubated with a large excess of alpha1-6-FucT. The fluorescent intensity of the fucosylated reaction product, which was analyzed by isocratic reverse phase HPLC, was proportional to the level of GDP-L-fucose in the microsomal fractions over the range 0.20-10 pmol. This assay is applicable to the determination of the GDP-L-fucose content in various cancer cell lines as well as rat liver and would be useful in developing a better understanding of the fucosylation potential of such cells and tissues.[1]
