Purity ~85% (SDS-PAGE). Catalyzes the formation of GDP-L-fucose from GTP and L-fucose-1-phosphate. Functions as a salvage pathway to reutilize L-fucose arising from the turnover of glycoproteins and glycolipids. Source: Recombinant protein corresponding to aa1-594 from human FPGT, fused to His-Tag at N-terminal, expressed in Yeast. Molecular Weight: ~68.6kD AA
