D-ribulokinase (EC 2.7.1.47) is an enzyme that catalyzes the chemical reaction
The enzyme characterised from Aerobacter aerogenes converts the pentose sugar, D-ribulose, (shown in its open-chain keto form) to D-ribulose-5-phosphate by transferring a phosphate group from the cofactor, adenosine triphosphate (ATP), which is converted to adenosine diphosphate (ADP). D-ribulose-5-phosphate is one of the end-products of the pentose phosphate pathway.[1] The enzyme is also found in yeast and mammals.[2]
It is a transferases, specifically one transferring phosphorus-containing groups (phosphotransferases) with an alcohol group as acceptor. The systematic name of this enzyme class is ATP:D-ribulose 5-phosphotransferase. It is also called D-ribulokinase (phosphorylating).[3]
