The acyl-CoA dehydrogenases are a family of related enzymes which catalyze the alpha,beta-dehydrogenation of acyl-CoA esters, transferring electrons to electron-transferring flavoprotein. A cDNA for human short/branched chain acyl-CoA dehydrogenase has recently been cloned, and it has been suggested that this enzyme represents the human homolog for the previously reported 2-methyl branched chain acyl-CoA dehydrogenase purified from rat liver. We now report the cloning and expression of rat short/branched chain acyl-CoA dehydrogenase and characterization of its substrate specificity. The rat enzyme is more active toward longer carbon side chains than its human counterpart, while the human enzyme can utilize substrates with longer primary carbon chains. In addition, short/branched chain acyl-CoA dehydrogenase can utilize valproyl-CoA as a substrate. Northern blotting of mRNA shows ubiquitous tissue expression of both the rat and human enzyme. Further study of these enzymes will be helpful in understanding structure/function relationships in this gene family. << Less

Purification and characterization of 2-methyl-branched chain acyl coenzyme A dehydrogenase, an enzyme involved in the isoleucine and valine metabolism, from rat liver mitochondria.

2-Methyl-branched chain acyl-CoA dehydrogenase was purified to homogeneity from rat liver mitochondria. The native molecular weight of the enzyme was estimated to be 170,000 by gel filtration.

2-Methyl-branched chain acyl-CoA dehydrogenase was purified to homogeneity from rat liver mitochondria. The native molecular weight of the enzyme was estimated to be 170,000 by gel filtration. On sodium dodecyl sulfate-polyacrylamide gel electrophoresis both with and without 2-mercaptoethanol, the enzyme showed a single protein band with Mr = 41,500, suggesting that this enzyme is composed of four subunits of equal size. Its isoelectric point was 5.50 +/-0.2, and A1%280 nm was 12.5. This enzyme contained protein-bound FAD. The purified enzyme dehydrogenated S-2-methylbutyryl-CoA and isobutyryl-CoA with equal activity. The activities with each of these compounds were co-purified throughout the entire purification procedure. This enzyme also dehydrogenated R-2-methylbutyryl-CoA, but the specific activity was considerably lower (22%) than that for the S-enantiomer. The enzyme did not dehydrogenate other acyl-CoAs, including isovaleryl-CoA, propionyl-CoA, butyryl-CoA, octanoyl-CoA, and palmitoyl-CoA, at any significant rate. Apparent Km and Vmax values for S-2-methylbutyryl-CoA were 20 microM and 2.2 mumol min-1 mg-1, respectively, while those for isobutyryl-CoA were 89 microM and 2.0 mumol min-1 mg-1 using phenazine methosulfate as an artificial electron acceptor. The enzyme was also active with electron transfer flavoprotein. Tiglyl-CoA and methacrylyl-CoA were identified as the reaction products from S-2-methylbutyryl-CoA and isobutyryl-CoA, respectively. 2-Ethylacrylyl-CoA was produced from R-2-methylbutyryl-CoA. Tiglyl-CoA competitively inhibited the activity with both S-2-methylbutyryl-CoA and isobutyryl-CoA with a similar Ki. The enzyme activity was also severely inhibited by several organic sulfhydryl reagents such as N-ethylmaleimide, p-hydroxymercuribenzoate, and methyl mercury iodide. The pattern and degree of inhibition were essentially identical for both substrates. The purified 2-methyl-branched chain acyl-CoA dehydrogenase was immunologically distinct from isovaleryl-CoA-, short chain acyl-CoA-, medium chain acyl-CoA-, or long chain acyl-CoA dehydrogenase. << Less
