CC   -!- FUNCTION: Involved in the catabolism of L-rhamnose (6-deoxy-L-mannose).
CC       Catalyzes the transfer of the gamma-phosphate group from ATP to the 1-
CC       hydroxyl group of L-rhamnulose to yield L-rhamnulose 1-phosphate.
CC       {ECO:0000255|HAMAP-Rule:MF_01535}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + L-rhamnulose = ADP + H(+) + L-rhamnulose 1-phosphate;
CC         Xref=Rhea:RHEA:20117, ChEBI:CHEBI:15378, ChEBI:CHEBI:17897,
CC         ChEBI:CHEBI:30616, ChEBI:CHEBI:58313, ChEBI:CHEBI:456216; EC=2.7.1.5;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01535};
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01535};
CC   -!- PATHWAY: Carbohydrate degradation; L-rhamnose degradation; glycerone
CC       phosphate from L-rhamnose: step 2/3. {ECO:0000255|HAMAP-Rule:MF_01535}.
CC   -!- SUBUNIT: Monomer. {ECO:0000255|HAMAP-Rule:MF_01535}.
CC   -!- SIMILARITY: Belongs to the rhamnulokinase family. {ECO:0000255|HAMAP-
CC       Rule:MF_01535}.
