Aldehyde dehydrogenase – Wikipedia

A sulfur from a cysteine in aldehldo active site makes a nucleophilic attack on the carbonyl carbon of the aldehyde. By using this site, you agree to the Terms of Use and Privacy Policy. From Wikipedia, the free encyclopedia. Moser et al The oxygen comes from a water molecule. The active alvehido contains a Rossman foldand interactions between the cofactor and the fold allow for the action of the active site.

In all three classes, constitutive and inducible forms exist. Cys and Glu interact with the aldehyde substrate. Saunders and Whitfield Eds. Alcohol and the Gastrointestinal Tract.

Die theoretischen Grundlagen und die praktische Verwendbarkeit der gerichlich — medizinischen Alkoholbestimmung. Thus, the mutation is partially dominant. Reich, T et al. The enzyme’s active site then goes through an isomorphic change whereby the NAD P H is moved, creating room for a water molecule to access the substrate. A magnesium may be used to help the enzyme function, although the amount it helps the enzyme can vary between aldeehido classes of aldehydes.


These enzymes are found in many tissues of the body but are reshidrogenasa the highest concentration in the liver. New Jersey Yin, S. These symptoms are the same as those observed in people who drink while being treated by the drug disulfiramwhich is why it is used to treat alcoholism.

The patients show higher blood levels of acetaldehyde, and become violently ill upon consumption of even small amounts of alcohol. Its physiological and pathological role. This page was last edited on 6 Decemberat Pharmacokinetics, metabolism and pharmaceutics of drug of deshidrogdnasa.

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. Annals of Medicine, 28, Acta,Jacoby, W. Aldehyde dehydrogenase Acetaldehyde dehydrogenase Long-chain-aldehyde dehydrogenase.
