Ethanolamine kinase

In enzymology, an ethanolamine kinase (EC 2.7.1.82) is an enzyme that catalyzes the chemical reaction

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.
