General description

Aldehyde dehydrogenases (ALDH) form a superfamily of phase-I oxidases and are evolutionarily conserved in eubacteria, eukaryotes, archaea, and other living organisms. ALDH is abundantly expressed in the liver and found in hepatic tissue. They are localized to the cytoplasm, mitochondria, endoplasmic reticulum, and nucleus.

Biochem/physiol Actions

Aldehyde dehydrogenases (ALDH) metabolize endogenous and exogenous reactive compounds to maintain cellular homeostasis. This group of enzymes catalyzes the NADP+-dependent irreversible oxidation of aldehydes to form carboxylic acids. ALDH isozymes have broad substrate specificity. Inactivation of ALDH causes cytotoxicity due to substrate accumulation.

Aldehyde dehydrogenases engage in many cellular functions, however their dysfunction resulting in accumulation of their substrates can be cytotoxic. ALDHs are responsible for the NAD(P)-dependent oxidation of aldehydes to carboxylic acids, participating in detoxification, biosynthesis, antioxidant and regulatory functions. Severe
