The patients show higher blood levels of acetaldehyde, and deshidrogenasz violently ill upon consumption of even small amounts of alcohol. 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.

The amino acid Glu is highlighted. Evidence for central ethanol oxidation. American Journal of Human Deshidrrogenasa. The active site of the aldehyde dehydrogenase enzyme is largely conserved throughout the different classes of the enzyme and, although the number of amino acids present in a subunit can change, the overall function of the site changes little. To date, nineteen ALDH genes have been identified within the human genome.

Statements and hypotheses of present research.

From Wikipedia, the free encyclopedia. A sulfur from a cysteine in the active site makes a nucleophilic attack on the carbonyl carbon of the aldehyde. Cys and Glu interact with the aldehyde substrate. Catalysis of coupled oxidation of alcools.

A magnesium may be used to help the enzyme function, although the amount it helps the enzyme can vary between different classes of aldehydes.
