Peroxisomal bifunctional protein from rat liver is a trifunctional enzyme possessing 2-enoyl-CoA hydratase, 3-hydroxyacyl-CoA dehydrogenase, and delta 3, delta 2-enoyl-CoA isomerase activities.

Peroxisomal delta 3, delta 2-enoyl-CoA isomerase (EC 5.3.3.8) was studied in the liver of rats treated with clofibrate. The mitochondrial and peroxisomal isoenzymes were separated chromatographically and the peroxisomal isomerase purified to apparent homogeneity. In addition to the isomerization of 3-enoyl-CoA esters, the purified protein also catalyzed hydration of trans-2-enoyl-CoA and oxidation of L-3-hydroxyacyl-CoA. Incubation of the purified protein with trans-3-decenoyl-CoA, NAD+, and Mg2+ resulted in an increase in absorbance at 303 nm, indicating the formation of 3-ketoacyl-CoA. The protein purified was monomeric, with an estimated molecular weight of 78,000. In immunoblotting it was recognized by the antibody to peroxisomal bifunctional protein from rat liver. Comparison of the amino acid sequences of cyanogen bromide cleaved isomerase with the known sequence of the peroxisomal bifunctional protein from the rat identified them as the same molecule. In control experiments, the peroxisomal bifunctional protein purified according to published methods also catalyzed delta 3, delta 2-enoyl-CoA isomerization. This means that the bifunctional protein of rat liver is in fact a trifunctional enzyme possessing delta 3, delta 2-enoyl-CoA isomerase, 2-enoyl-CoA hydratase (EC 4.2.1.17), and L-3-hydroxyacyl-CoA dehydrogenase (EC 1.1.1.35) activities in the same polypeptide. << Less

Functional characterization of delta3,delta2-enoyl-CoA isomerases from rat liver.
Zhang D., Yu W., Geisbrecht B.V., Gould S.J., Sprecher H., Schulz H.
The degradation of unsaturated fatty acids by beta-oxidation involves Delta(3),Delta(2)-enoyl-CoA isomerases (enoyl-CoA isomerases) that catalyze 3-cis --> 2-trans and 3-trans --> 2-trans isomerizations of enoyl-CoAs and the 2,5 --> 3,5 isomerization of dienoyl-CoAs.

The degradation of unsaturated fatty acids by beta-oxidation involves Delta(3),Delta(2)-enoyl-CoA isomerases (enoyl-CoA isomerases) that catalyze 3-cis --> 2-trans and 3-trans --> 2-trans isomerizations of enoyl-CoAs and the 2,5 --> 3,5 isomerization of dienoyl-CoAs. An analysis of rat liver enoyl-CoA isomerases revealed the presence of a monofunctional enoyl-CoA isomerase (ECI) in addition to mitochondrial enoyl-CoA isomerase (MECI) in mitochondria, whereas peroxisomes contain ECI and multifunctional enzyme 1 (MFE1). Thus ECI, which previously had been described as peroxisomal enoyl-CoA isomerase, was found to be present in both peroxisomes and mitochondria. This enzyme seems to be identical with mitochondrial long-chain enoyl-CoA isomerase (Kilponen, J.M., Palosaari, P.M., and Hiltunen, J.K. 1990. Biochem. J. 269, 223-226). All three hepatic enoyl-CoA isomerases have broad chain length specificities but are distinguishable by their preferences for one of the three isomerization reactions. MECI is most active in catalyzing the 3-cis --> 2-trans isomerization; ECI has a preference for the 3-trans --> 2-trans isomerization, and MFE1 is the optimal isomerase for the 2,5 --> 3,5 isomerization. A functional characterization based on substrate specificities and total enoyl-CoA isomerase activities in rat liver leads to the conclusion that the 3-cis --> 2-trans and 2,5 --> 3,5 isomerizations in mitochondria are catalyzed overwhelmingly by MECI, whereas ECI contributes significantly to the 3-trans --> 2-trans isomerization. In peroxisomes, ECI is predicted to be the dominant enzyme for the 3-cis --> 2-trans and 3-trans --> 2-trans isomerizations of long-chain intermediates, whereas MFE1 is the key enzyme in the 2,5 --> 3,5 isomerization. << Less
