In enzymology a xylitol kinase (EC 2.7.1.122) is an enzyme that catalyzes the chemical reactionATP + xylitol ADP + xylitol 5-phosphateThus 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.
