In enzymology, an ethanolamine ammonia-lyase (EC 22.214.171.124) is an enzyme that catalyzes the chemical reaction
- ethanolamine acetaldehyde + NH3
Hence, this enzyme has one substrate, ethanolamine, and two products, acetaldehyde and NH3.
This enzyme belongs to the family of lyases, specifically ammonia lyases, which cleave carbon-nitrogen bonds. The systematic name of this enzyme class is ethanolamine ammonia-lyase (acetaldehyde-forming). This enzyme is also called ethanolamine deaminase. This enzyme participates in glycerophospholipid metabolism. It employs one cofactor, adenosylcobalamin.
