What is "mannokinase"

n. (context biochemistry English) An enzyme, ATP:D-mannose 6-phosphotransferase.

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

ATP + D-mannose $\rightleftharpoons$ ADP + D-mannose 6-phosphate

Thus, the two substrates of this enzyme are ATP and D-mannose, whereas its two products are ADP and D-mannose 6-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:D-mannose 6-phosphotransferase. Other names in common use include mannokinase (phosphorylating), and D-fructose (D-mannose) kinase. This enzyme participates in fructose and mannose metabolism.
