The enzyme ethanolamine-phosphate phospho-lyase (EC 4.2.3.2) catalyzes the chemical reaction
This enzyme belongs to the family of lyases, specifically those carbon-oxygen lyases acting on phosphates. The systematic name of this enzyme class is ethanolamine-phosphate phosphate-lyase (deaminating; acetaldehyde-forming). Other names in common use include O-phosphoethanolamine-phospholyase, amino alcohol O-phosphate phospholyase, O-phosphorylethanol-amine phospho-lyase, and ethanolamine-phosphate phospho-lyase (deaminating). It employs one cofactor, pyridoxal phosphate.
