Structural Basis of Substrate Recognition by Aldehyde Dehydrogenase 7A1
Aldehyde dehydrogenase 7A1 (ALDH7A1) is part of lysine catabolism and catalyzes the NAD(+)-dependent oxidation of α-aminoadipate semialdehyde to α-aminoadipate. Herein, we describe a structural study of human ALDH7A1 focused on substrate recognition. Five crystal structures and small-angle X-ray scattering data are reported, including the first crystal structure of any ALDH7 family member compl...
متن کاملImportance of the C-Terminus of Aldehyde Dehydrogenase 7A1 for Oligomerization and Catalytic Activity.
Aldehyde dehydrogenase 7A1 (ALDH7A1) catalyzes the terminal step of lysine catabolism, the NAD+-dependent oxidation of α-aminoadipate semialdehyde to α-aminoadipate. Structures of ALDH7A1 reveal the C-terminus is a gate that opens and closes in response to the binding of α-aminoadipate. In the closed state, the C-terminus of one protomer stabilizes the active site of the neighboring protomer in...
متن کاملHorse Liver Aldehyde Dehydrogenase
Horse liver aldehyde: NAD oxidoreductase (EC 1.2.1.3) has been purified to homogeneity by a procedure consisting of salt fractionation, ion exchange chromatography, and isoelectric focusing. The purif?ed material has a turnover number of 1.85 pmoles of NADH per min per mg of protein when assayed at pH 9.0 with propionaldehyde as substrate. Values obtained for the molecular weight of the native ...
متن کاملAldehyde dehydrogenase. Covalent intermediate in aldehyde dehydrogenation and ester hydrolysis.
4-trans-(NN-Dimethylamino)cinnamaldehyde (an aldehyde, DACA) and 4-trans-(NN-dimethylamino)cinnamoylimidazole (an amide, DACI) have been shown to be substrates for human aldehyde dehydrogenase (EC 1.2.1.3) which form chromophoric covalent intermediates. The spectra of covalent intermediates from both the cytoplasmic (E1) and mitochondrial (E2) isoenzymes derived from DACA and DACI were compared...
متن کاملHuman Liver Aldehyde Dehydrogenase
Human liver aldehyde dehydrogenase has been found to be capable of hydrolyzing p-nitrophenyl esters. Esterase and dehydrogenase activities exhibited identical ion exchange and affinity properties, indicating that the same protein catalyzes both reactions. Competitive inhibition of esterase activity by glyceraldehyde and chloral hydrate furnished evidence that p-nitrophenyl acetate was hydrolyze...
