ATP + L-xylulose ADP + L-xylulose 5-phosphate

Thus, the two substrates of this enzyme are ATP and L-xylulose, whereas its two products are ADP and L-xylulose 5-phosphate.

This enzyme belongs to the family of transferases, specifically those transferring phosphorus-containing groups (phosphotransferases) with an alcohol group as acceptor. The systematic name of this enzyme class is ATP:L-xylulose 5-phosphotransferase. This enzyme is also called L-xylulokinase (phosphorylating). This enzyme participates in pentose and glucuronate interconversions and ascorbate and aldarate metabolism.
