Ethanolamine ammonia-lyase

In enzymology, an ethanolamine ammonia-lyase is an enzyme that catalyzes the chemical reaction


 * ethanolamine $$\rightleftharpoons$$ 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, cobamide.

Structural studies
As of late 2007, only one structure has been solved for this class of enzymes, with the PDB accession code.
