The water is primed by a glutamate in the active site, and the water makes a nucleophilic attack on the carbonyl carbon, kicking off the sulfur as a leaving group. Cloning and characterisation of rabbit liver isoforms of the enzyme. ALDH2 plays a crucial role in maintaining low blood levels of acetaldehyde during alcohol oxidation.

Aldehyde dehydrogenases EC 1. The metabolized acetaldehyde in the blood, which is six times higher than in individuals without the mutation, has shown to be a carcinogen in lab animals.

These enzymes are found in many tissues of the body but are at the highest concentration in the liver. These symptoms are the same as those observed in people who drink while adlehido treated by the drug disulfiramwhich is why it is used to treat alcoholism.

An important determinant of blood levels after alcohol consumption. A magnesium may be used to help the enzyme function, although the amount it helps the enzyme can vary between different classes of aldehydes.
