Catalyzes the formation of GDP-L-fucose from GTP and L-fucose-1-phosphate (PubMed:9804772). Functions as a salvage pathway to reutilize L-fucose arising from the turnover of glycoproteins and glycolipids (PubMed:9804772). beta-L-fucose 1-phosphate + GTP + H(+) = diphosphate + GDP-beta-L-fucose Optimum pH is 6.8 to 7.8.
