Saunders and Whitfield Eds. An important determinant of blood levels after alcohol consumption. Reich, T et al. The water is primed by aldrhido glutamate in the active site, and deshkdrogenasa water makes a nucleophilic attack on the carbonyl carbon, kicking off the sulfur as a leaving group.
Enzimas del metabolismo del etanol: Aldehyde dehydrogenase Acetaldehyde dehydrogenase Long-chain-aldehyde dehydrogenase. Annals of Medicine, 28, Effects on Biological Membranes. The oxygen comes from a water molecule. Nippon Rinsho, 53, Evidence for central ethanol oxidation. Cys and Glu interact with the aldehyde substrate. Die theoretischen Grundlagen und die praktische Verwendbarkeit der gerichlich — medizinischen Alkoholbestimmung. ALDH2 plays a crucial role in maintaining low blood levels of acetaldehyde during alcohol oxidation.
Knockout mouse models further confirm the involvement of ALDH family in neurodegeneration. These enzymes are found in many tissues of the body but are at the highest concentration in the liver.
These genes participate in a wide variety of biological processes including the detoxification of exogenously and endogenously generated aldehydes.
In this pathway, the intermediate structures can be toxic, and health problems arise when those intermediates cannot be cleared. The active site contains a Rossman foldand interactions between the cofactor and the fold allow for the action of the active site. Allosteric regulation Cooperativity Enzyme inhibitor Enzyme activator.
Structural basis for substrate specificity.
The active site of a human mitochondrial aldehyde dehydrogenase 2. To date, nineteen ALDH genes have been identified within the human genome.
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. Pharmacokinetics, metabolism and pharmaceutics of drug of abuse. Molecular and Cellular Biology portal. Acta,Jacoby, W.

Not to be confused with aldehyde oxidase. Moser et al A sulfur from a cysteine in the active site makes a nucleophilic attack on the carbonyl carbon of the aldehyde.
