It could also play a role in the metabolism of some rare sugars such as L-fructose. Catalyzes the transfer of the gamma-phosphate group from ATP to the 1-hydroxyl group of L-rhamnulose to yield L-rhamnulose 1-phosphate. It can also phosphorylate L-fuculose and L-xylulose. It requires the R-configuration at the C-3 atom.[HAMAP-Rule:MF_01535]<ref>PMID:17568582</ref> | |

The enzyme L-rhamnulose kinase from Escherichia coli participates in the degradation pathway of L-rhamnose, a common natural deoxy-hexose. The structure of the enzyme in a ternary complex with its substrates ADP and L-rhamnulose has been determined at 1.55A resolution and refined to R(cryst)/R(free) values of 0.179/0.209. The result was compared with the lower resolution structure of a corresponding complex containing L-fructose instead of L-rhamnulose. In light of the two established sugar positions and conformations, a number of rare sugars have been modeled into the active center of L-rhamnulose kinase and the model structures have been compared with the known enzymatic phosphorylation rates. Rare sugars are of rising interest for the synthesis of bioactive compounds. | The enzyme L-rhamnulose kinase from Escherichia coli participates in the degradation pathway of L-rhamnose, a common natural deoxy-hexose.
