Purified recombinant Human ALDH2 protein Expression System: E.coli Bioactivity: Specific activity is < 0.2 units/mL, and was obtained by measuring the increase of NADP in absorbance at 340 nm resulting from the reduction of NAD. One unit will oxidize 1.0 uM of acetaldehyde to acetic acid per minute at pH 8.0 at 25 °C in the presence of beta-NAD, potassium and thiols. Molecular weight on SDS-PAGE will appear higher.

(Aldehyde Dehydrogenase 2 Family (Mitochondrial) (ALDH2))
ALDH2 (Aldehyde dehydrogenase 2 family) belongs to the aldehyde dehydrogenase family which catalyze the chemical transformation from acetaldehyde to acetic acid and is the second enzyme of the major oxidative pathway of alcohol metabolism. There are two major liver isoforms of this enzyme, cytosolic and mitochondrial, and they can be also distinguished by their electrophoretic mobilities, kinetic properties, and subcellular localizations. Recombinant human ALDH2 protein was expressed in E. coli and purified by using conventional chromatography techniques.
