Xylitol kinase

In enzymology, a xylitol kinase (EC 2.7.1.122) is an enzyme that catalyzes the chemical reaction

Thus, the two substrates of this enzyme are ATP and xylitol, whereas its two products are ADP and xylitol 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:xylitol 5-phosphotransferase.
