In enzymology, a xylitol kinase (EC 2.7.1.122) is an enzyme that catalyzes the chemical reaction
- ATP + xylitol [math]\displaystyle{ \rightleftharpoons }[/math] ADP + xylitol 5-phosphate
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.
