CC   -!- FUNCTION: Highly specific D-xylulose kinase which participates in the
CC       catabolism of xylose. Xylose is a major component of hemicelluloses
CC       such as xylan. Most fungi utilize D-xylose via three enzymatic
CC       reactions, xylose reductase (XR), xylitol dehydrogenase (XDH), and
CC       xylulokinase, to form xylulose 5-phosphate, which enters pentose
CC       phosphate pathway (By similarity). {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + D-xylulose = ADP + D-xylulose 5-phosphate + H(+);
CC         Xref=Rhea:RHEA:10964, ChEBI:CHEBI:15378, ChEBI:CHEBI:17140,
CC         ChEBI:CHEBI:30616, ChEBI:CHEBI:57737, ChEBI:CHEBI:456216;
CC         EC=2.7.1.17;
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC   -!- INDUCTION: By D-xylose, L-arabinose or L-arabitol.
CC   -!- SIMILARITY: Belongs to the FGGY kinase family. {ECO:0000305}.
