General annotation (Comments)

Function	Highly specific D-xylulose kinase which participates in the catabolism of xylose. Xylose is a major component of hemicelluloses such as xylan. Most fungi utilize D-xylose via three enzymatic reactions, xylose reductase (XR), xylitol dehydrogenase (XDH), and xylulokinase, to form xylulose 5-phosphate, which enters pentose phosphate pathway By similarity.
Catalytic activity	ATP + D-xylulose = ADP + D-xylulose 5-phosphate.
Subcellular location	Cytoplasm By similarity.
Induction	By D-xylose, L-arabinose or L-arabitol.
Sequence similarities	Belongs to the FGGY kinase family.
