In enzymology, an alkylglycerone kinase () is an enzyme that catalyzes the chemical reaction
Thus, the two substrates of this enzyme are ATP and O-alkylglycerone, whereas its two products are ADP and O-alkylglycerone 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:O-alkylglycerone phosphotransferase. Other names in common use include alkyldihydroxyacetone kinase (phosphorylating), and alkyldihydroxyacetone kinase.
