What is "rhamnulokinase"

n. (context enzyme English) A transferase enzyme that catalyzes the chemical reaction ''ATP + L-rhamnulose $rightleftharpoons$ ADP + L-rhamnulose 1-phosphate''.

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

ATP + L-rhamnulose $\rightleftharpoons$ 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.
