In enzymology, a serine-ethanolaminephosphate phosphodiesterase (EC 3.1.4.13) is an enzyme that catalyzes the chemical reaction
- serine phosphoethanolamine + H2O serine + ethanolamine phosphate
Thus, the two substrates of this enzyme are serine phosphoethanolamine and H2O, whereas its two products are serine and ethanolamine phosphate.
This enzyme belongs to the family of hydrolases, specifically those acting on phosphoric diester bonds. The systematic name of this enzyme class is serine-phosphoethanolamine ethanolaminephosphohydrolase. Other names in common use include serine ethanolamine phosphodiester phosphodiesterase, and SEP diesterase. This enzyme participates in glycerophospholipid metabolism.
