Application
Biochem/physiol Actions
ADH (alcohol dehydrogenase) is one of the first enzymes to be isolated and purified. NAD+ is its coenzyme. Three isozymes of yeast ADH, that is, yeast alcohol dehydrogenase-1, 2 and 3 (YADH-1, -2, -3) have been identified. YADH-1 is expressed during anaerobic fermentation, YADH-2 is expressed in the cytoplasm and YADH-3 is localized to the mitochondria. A 141kDa tetramer containing 4 equal subunits. The active site of each subunit contains a zinc atom. Each active site also contains 2 reactive sulfhydryl groups and a histidine residue.
Isoelectric point: 5.4-5.8
Optimal pH: 8.6-9.0
Substrates: Yeast ADH is most active with ethanol and its activity decreases as the size of the alcohol increases or decreases. Branched chain alcohols and secondary alcohols also have very low activity.
KM (ethanol) = 2.1 × 10-2 M
KM (methanol = 1.3 × 10-1 M
KM (isopropanol) = 1.4 × 10-1 M
Inhibitors: Compounds that react with free sulfhydryls, including N-alkylmaleimides and iodoacetamide.
Zinc chelator inhibitors, including 1,10-phenanthroline,
8-hydroxyquinoline, 2,2′-dipyridyl, and thiourea.
Substrate analogue inhibitors, including β-NAD analogs, purine and pyrimidine derivatives, chloroethanol, and fluoroethanol.
Extinction Coefficient: E1% = 14.6 (water, 280 nm)

Yeast alcohol dehydrogenase 1 (YADH1) catalyzes the conversion of acetaldehyde to ethanol during glucose fermentation pathway.[5] It is also implicated in the production of alcohol from amino acid breakdown via the Ehrlich pathway.
Features and Benefits
The dried enzyme has been stored for several weeks in a vacuum desiccator with little loss in activity. According to experiments described by A. Kornberg,3 the enzyme can be stored in the frozen state and can be thawed repeatedly without marked loss of activity.
Physical form
Solids containing <2% citrate buffer salts
Other Notes
One unit will convert 1.0 μmole of ethanol to acetaldehyde per min at pH 8.8 at 25 °C.
