==Structure of L-rhamnulose kinase in complex with ADP and beta-L- rhamnulose.==
-
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.

[https://www.uniprot.org/uniprot/RHAB_ECOUT RHAB_ECOUT] Involved in the catabolism of L-rhamnose (6-deoxy-L-mannose). 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>
