Xylulokinase

In enzymology, a xylulokinase (EC number|2.7.1.17) is an enzyme that catalyzes the chemical reaction

:ATP + D-xylulose $ightleftharpoons$ ADP + D-xylulose 5-phosphate

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.

tructural studies

As of late 2007, two structures have been solved for this class of enzymes, with PDB accession codes PDB link|2ITM and PDB link|2NLX.
