The gene name used for the gene that encodes L-fuculokinase is fucK.
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.
