What is "fucokinase"

In enzymology, a fucokinase is an enzyme that catalyzes the chemical reaction

ATP + L-fucose $\rightleftharpoons$ ADP + beta-L-fucose 1-phosphate

Thus, the two substrates of this enzyme are ATP and L-fucose, whereas its two products are ADP and beta-L-fucose 1-phosphate.

This enzyme 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:beta-L-fucose 1-phosphotransferase. Other names in common use include fucokinase (phosphorylating), fucose kinase, L-fucose kinase, L-fucokinase, ATP:6-deoxy-L-galactose 1-phosphotransferase, and ATP:L-fucose 1-phosphotransferase. Fucokinase is commonly abbreviated as fuc-K. This enzyme participates in fructose and mannose metabolism.
