In enzymology, a sedoheptulokinase (EC 188.8.131.52) is an enzyme that catalyzes the chemical reaction
ATP + sedoheptulose
ADP + sedoheptulose 7-phosphate
Thus, the two substrates of this enzyme are ATP and sedoheptulose, whereas its two products are ADP and sedoheptulose 7-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:sedoheptulose 7-phosphotransferase. Other names in common use include heptulokinase, and sedoheptulokinase (phosphorylating). This enzyme participates in carbon fixation.
