In enzymology, an ethanolamine kinase (EC 2.7.1.82) is an enzyme that catalyzes the chemical reaction
- ATP + ethanolamine ADP + O-phosphoethanolamine
Thus, the two substrates of this enzyme are ATP and ethanolamine, whereas its two products are ADP and O-phosphoethanolamine.
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:ethanolamine O-phosphotransferase. Other names in common use include ethanolamine kinase (phosphorylating), and ethanolamine phosphokinase. This enzyme participates in glycerophospholipid metabolism.
