Purification and characterization of short-chain, medium-chain, and long-chain acyl-CoA dehydrogenases from rat liver mitochondria. Isolation of the holo- and apoenzymes and conversion of the apoenzyme to the holoenzyme.

Short-chain, medium-chain, and long-chain acyl-CoA dehydrogenases were purified to homogeneity from rat liver mitochondria by sequential chromatography on DEAE-Sephadex A-50, hydroxyapatite, Matrex Gel Blue A, agarose-hexane-CoA, and Bio-Gel A-0.5m.

Short-chain, medium-chain, and long-chain acyl-CoA dehydrogenases were purified to homogeneity from rat liver mitochondria by sequential chromatography on DEAE-Sephadex A-50, hydroxyapatite, Matrex Gel Blue A, agarose-hexane-CoA, and Bio-Gel A-0.5m. Molecular, immunological, and catalytic properties of the pure acyl-CoA dehydrogenases were investigated. The native molecular weights of these three enzymes were 160,000, 180,000, and 180,000, respectively. The subunit molecular weights of the three enzymes were estimated to be 41,000, 45,000, and 45,000, respectively, indicating that these enzymes are each composed of four subunits of equal size. The FAD content was calculated to be 1 mol/mol of subunit. While FAD binding by short-chain acyl-CoA dehydrogenase was very tight, that by medium-chain acyl-CoA and long-chain acyl-CoA dehydrogenases was less tight. The medium- and long-chain acyl-CoA dehydrogenases were also purified to homogeneity as FAD-free apoenzymes. The apoenzymes were converted to the fully active holoenzymes by incubation with FAD. The three acyl-CoA dehydrogenases were immunologically distinct from each other, i.e. the antibodies raised against the individual enzymes were monospecific and did not cross-react with any other acyl-CoA dehydrogenases. Our preparations of the three enzymes exhibited substrate specificities (as defined in Vappmax and Kappmax) significantly more specific than those of the previous preparations isolated from other sources. The substrate specificities were assessed also by measuring the activities in mitochondrial sonicates after selectively precipitating each enzyme with their individual monospecific antibodies. Butyryl-CoA was almost exclusively dehydrogenated by short-chain acyl-CoA dehydrogenase while C6-C10 acyl-CoAs were mainly dehydrogenated by medium-chain acyl-CoA dehydrogenase. C14-C22 acyl-CoAs were exclusively dehydrogenated by long-chain acyl-CoA dehydrogenase. C24 acyl-CoAs were not dehydrogenated by this enzyme. Lauroyl-CoA appeared to be jointly dehydrogenated by the latter two enzymes. Branched-chain acyl-CoAs were not dehydrogenated by short-chain acyl-CoA dehydrogenase. In the presence of electron-transfer flavoprotein or phenazine methosulfate, 2-enoyl-CoAs were identified as products from the corresponding enzyme/acyl-CoA reactions. << Less

We have used molecular modeling and site-directed mutagenesis to identify the catalytic residues of human long chain acyl-CoA dehydrogenase. Among the acyl-CoA dehydrogenases, a family of flavoenzymes involved in beta-oxidation of fatty acids, only the three-dimensional structure of the medium chain fatty acid specific enzyme from pig liver has been determined (Kim, J.-J.P., Wang, M., & Paschke, R. (1993) Proc. Natl. Acad. Sci. U.S.A. 90, 7523-7527). Despite the overall sequence homology, the catalytic residue (E376) of medium chain acyl-CoA dehydrogenase is not conserved in isovaleryl- and long chain acyl-CoA dehydrogenases. A molecular model of human long chain acyl-CoA dehydrogenase was derived using atomic coordinates determined by X-ray diffraction studies of the pig medium chain specific enzyme, interactive graphics, and molecular mechanics calculations. The model suggests that E261 functions as the catalytic base in the long-chain dehydrogenase. An altered dehydrogenase in which E261 was replaced by a glutamine was constructed, expressed, purified, and characterized. The mutant enzyme exhibited less than 0.02% of the wild-type activity. These data strongly suggest that E261 is the base that abstracts the alpha-proton of the acyl-CoA substrate in the catalytic pathway of this dehydrogenase. << Less
