human ... ALDH2(217)

General description

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. ALDH2 has been shown to interact with GroEL.
ALDH2 (Aldehyde dehydrogenase 2 family) belongs to the aldehyde dehydrogenase family. There are two major liver isoforms of liver aldehyde dehydrogenase, cytosolic (ALDH1) and mitochondrial (ALDH2), and they can be distinguished by their electrophoretic mobilities, kinetic properties, and subcellular localizations.
The ALDH2 gene is mapped to human chromosome 12q24.12.

Biochem/physiol Actions

Aldehyde dehydrogenases catalyze the chemical transformation from acetaldehyde to acetic acid and ALDH2 (Aldehyde dehydrogenase 2 family) is the major enzyme of the oxidative pathway of alcohol metabolism. Overexpression of ALDH2 inhibits cell injury induced by acetaldehyde and prevents activation of stress signals.
It is actively involved in the metabolism of both endogenous and exogenous substances.

Physical form

1 mg/mL solution in 20 mM Tris-HCl buffer (pH 7.5) containing 1 mM DTT, 1 mM EDTA and 10% glycerol.
