Accepted name: fucokinase
Reaction: ATP + L-fucose = ADP + β-L-fucose 1-phosphate

Other name(s): fucokinase (phosphorylating); fucose kinase; L-fucose kinase; L-fucokinase; ATP:6-deoxy-L-galactose 1-phosphotransferase; ATP:L-fucose 1-phosphotransferase
Systematic name: ATP:β-L-fucose 1-phosphotransferase
Comments: Requires a divalent cation for activity, with Mg2+ and Fe2+ giving rise to the highest enzyme activity. Forms part of a salvage pathway for reutilization of L-fucose. Can also phosphorylate D-arabinose, but more slowly.
