Welcome to ALDHs !

The aldehyde dehydrogenase (ALDH) superfamily is part of a conserved gene superfamily encoding NAD(P)+-dependent enzymes that catalyze the irreversible oxidation of endogenous and exogenous aromatic and aliphatic aldehydes into non-toxic carboxylic acids. In addition, under conditions that induce oxidative stress, ALDH enzymes act as 'aldehyde scavengers' by metabolizing reactive aldehydes derived from the oxidative degradation of lipid membranes, also known as lipid peroxidation. Many of the plant ALDH genes characterized thus far are responsive to various types of stress, including dehydration, water logging, exposure to heavy metals, high salinity, oxidative stress, and ultraviolet radiation (UVR), suggesting possible roles for these genes in improving stress tolerance.
