Rhamnulokinase

In enzymology, a rhamnulokinase (EC number|2.7.1.5) is an enzyme that catalyzes the chemical reaction

:ATP + L-rhamnulose $$ightleftharpoons ADP + L-rhamnulose 1-phosphate

Thus, the two substrates of this enzyme are ATP and L-rhamnulose, whereas its two products are ADP and L-rhamnulose 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:L-rhamnulose 1-phosphotransferase. Other names in common use include RhuK, rhamnulokinase (phosphorylating), L-rhamnulokinase, L-rhamnulose kinase, and rhamnulose kinase. This enzyme participates in pentose and glucuronate interconversions and fructose and mannose metabolism.
