WebALDH has an ancient origin and is found in all living organisms from Archaea and Eubacteria to eukaryotes ( 131, 291 ). Complete human genome and expression studies … Aldehyde dehydrogenases (ALDH) (EC 1.2.1.3) are a family of nicotinamide adenine dinucleotide (phosphate) (NAD (P)) dependent enzymes, typically with a molecular mass of ca. 50–60 kDa. They oxidise a large range of aliphatic and aromatic, endogenous and exogenous aldehydes to form the … See more ALDH enzymes typically exist and function as homotetramers or homodimers (Figures 1A,B) formed by subunits of approximately 450–500 amino acids to construct a 50–60 kDa protomer. … See more The active site of the ALDH is located at the base of a hydrophobic, funnel shaped tunnel, close to the subunit’s interface and opposite the cofactor binding site. A highly reactive active-site … See more As previously stated ALDHs exist in dimeric or tetrameric state, but a small number of resolved structures have now demonstrated the presence of hexameric enzymes. ALDHs are … See more A selection of enzymes use dinucleotide cofactors, such as NAD or flavin adenine dinucleotide (FAD), and even though their overall enzyme … See more
