Comments
[?]
| FUNCTION | Involved in the catabolism of L-rhamnose (6-deoxy-L-mannose). Catalyzes the transfer of the gamma-phosphate group from ATP to the 1- hydroxyl group of L-rhamnulose to yield L-rhamnulose 1-phosphate. |
| CATALYTIC ACTIVITY | Reaction=ATP + L-rhamnulose = ADP + H(+) + L-rhamnulose 1-phosphate; Xref=Rhea:RHEA:20117, ChEBI:CHEBI:15378, ChEBI:CHEBI:17897, ChEBI:CHEBI:30616, ChEBI:CHEBI:58313, ChEBI:CHEBI:456216; EC=2.7.1.5; |
| COFACTOR | Name=Mg(2+); Xref=ChEBI:CHEBI:18420; |
| PATHWAY | Carbohydrate degradation; L-rhamnose degradation; glycerone phosphate from L-rhamnose: step 2/3. |
| case <OC:Escherichia> | |
| SUBUNIT | Monomer. |
| end case | |
| SIMILARITY | Belongs to the rhamnulokinase family. |
