L-Fuculokinase ({{EC number|2.7.1.51}}) is an enzyme that catalyzes the chemical reaction

: ATP + L-fuculose (L-fuculokinase) {{eqm}} ADP + L-fuculose-1-phosphate

Thus, the two substrates of this enzyme are ATP and L-fuculose, whereas its two products are ADP and L-fuculose-1-phosphate.{{cite journal |vauthors=Heath EC, Ghalambor MA | year = 1962 | title = The metabolism of L-fucose.

The gene name used for the gene that encodes L-fuculokinase is fucK.{{cite web|url=https://www.ncbi.nlm.nih.gov/gene/958268|date=2010-02-07|publisher=National Center for Biotechnology Information|title=NCBI gene database entry for E. coli O157:H7 fucK|accessdate=20 February 2010}}

L-Fuculokinase belongs to the family of transferases, specifically those transferring phosphorus-containing groups (phosphotransferases) with an alcohol group as acceptor. The systematic name of this enzyme class is ATP:L-fuculose 1-phosphotransferase. Other names in common use include L-fuculokinase (phosphorylating), and L-fuculose kinase. This enzyme participates in fructose and mannose metabolism.
