Xylulokinase

In enzymology, a xylulokinase (EC2.7.1.17) is an enzyme that catalyzes the chemical reaction

Thus, the two substrates of this enzyme are ATP and D-xylulose, whereas its two products are ADP and D-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:D-xylulose 5-phosphotransferase. Other names in common use include xylulokinase (phosphorylating), and D-xylulokinase. This enzyme participates in pentose and glucuronate interconversions.
