• Source: D-ribulokinase

In enzymology, a D-ribulokinase (EC 2.7.1.47) is an enzyme that catalyzes the chemical reaction

ATP + D-ribulose



⇌


{\displaystyle \rightleftharpoons }

ADP + D-ribulose 5-phosphate
Thus, the two substrates of this enzyme are ATP and D-ribulose, whereas its two products are ADP and D-ribulose 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-ribulose 5-phosphotransferase. This enzyme is also called D-ribulokinase (phosphorylating). This enzyme participates in pentose and glucuronate interconversions.
