Expression and initial characterization of human ALDH3B1.
Marchitti S.A., Orlicky D.J., Vasiliou V.
Aldehyde dehydrogenases (ALDHs) are critical enzymes in the metabolism of endogenous and exogenous aldehydes. The human genome contains 19 putatively functional ALDH genes; ALDH3B1 belongs to the ALDH3 family. While recent studies have linked the ALDH3B1 locus to schizophrenia, nothing was known, ... >> More
Aldehyde dehydrogenases (ALDHs) are critical enzymes in the metabolism of endogenous and exogenous aldehydes. The human genome contains 19 putatively functional ALDH genes; ALDH3B1 belongs to the ALDH3 family. While recent studies have linked the ALDH3B1 locus to schizophrenia, nothing was known, until now, about the properties and significance of the ALDH3B1 protein. The aim of this study was to characterize the ALDH3B1 protein. Human ALDH3B1 was baculovirus-expressed and found to be catalytically active towards medium- and long-chain aliphatic aldehydes and the aromatic aldehyde benzaldehyde. Western blot analyses indicate that ALDH3B1 is highly expressed in kidney and liver and moderately expressed in various brain regions. ALDH3B1-transfected HEK293 cells were significantly protected against cytotoxicity induced by the lipid peroxidation product octanal when compared to vector-transfected cells. This study shows for the first time the functionality, expression and protective role of ALDH3B1 and indicates a potential physiological role of ALDH3B1 against oxidative stress. << Less

Aldehyde dehydrogenase 7A1 (ALDH7A1) is a novel enzyme involved in cellular defense against hyperosmotic stress.
Brocker C., Lassen N., Estey T., Pappa A., Cantore M., Orlova V.V., Chavakis T., Kavanagh K.L., Oppermann U., Vasiliou V.
Mammalian ALDH7A1 is homologous to plant ALDH7B1, an enzyme that protects against various forms of stress, such as salinity, dehydration, and osmotic stress. It is known that mutations in the human ALDH7A1 gene cause pyridoxine-dependent and folic acid-responsive seizures. Herein, we show for the ... >> More
Mammalian ALDH7A1 is homologous to plant ALDH7B1, an enzyme that protects against various forms of stress, such as salinity, dehydration, and osmotic stress. It is known that mutations in the human ALDH7A1 gene cause pyridoxine-dependent and folic acid-responsive seizures. Herein, we show for the first time that human ALDH7A1 protects against hyperosmotic stress by generating osmolytes and metabolizing toxic aldehydes. Human ALDH7A1 expression in Chinese hamster ovary cells attenuated osmotic stress-induced apoptosis caused by increased extracellular concentrations of sucrose or sodium chloride. Purified recombinant ALDH7A1 efficiently metabolized a number of aldehyde substrates, including the osmolyte precursor, betaine aldehyde, lipid peroxidation-derived aldehydes, and the intermediate lysine degradation product, alpha-aminoadipic semialdehyde. The crystal structure for ALDH7A1 supports the enzyme's substrate specificities. Tissue distribution studies in mice showed the highest expression of ALDH7A1 protein in liver, kidney, and brain, followed by pancreas and testes. ALDH7A1 protein was found in the cytosol, nucleus, and mitochondria, making it unique among the aldehyde dehydrogenase enzymes. Analysis of human and mouse cDNA sequences revealed mitochondrial and cytosolic transcripts that are differentially expressed in a tissue-specific manner in mice. In conclusion, ALDH7A1 is a novel aldehyde dehydrogenase expressed in multiple subcellular compartments that protects against hyperosmotic stress by generating osmolytes and metabolizing toxic aldehydes. << Less
