Rat peroxisomal multifunctional enzyme type 1 (perMFE-1) is a monomeric protein of beta-oxidation. We have defined five functional domains (A, B, C, D and E) in the perMFE-1 based on comparison of the amino acid sequence with homologous proteins from databases and structural data of the hydratase-1/isomerases (H1/I) and (3 S )-hydroxyacyl-CoA dehydrogenases (HAD). Domain A (residues 1-190) comprises the H1/I fold and catalyses both 2-enoyl-CoA hydratase-1 and Delta(3)-Delta(2)-enoyl-CoA isomerase reactions. Domain B (residues 191-280) links domain A to the (3 S )-dehydrogenase region, which includes both domain C (residues 281-474) and domain D (residues 480-583). Domains C and D carry features of the dinucleotide-binding and the dimerization domains of monofunctional HADs respectively. Domain E (residues 584-722) has sequence similarity to domain D of the perMFE-1, which suggests that it has evolved via partial gene duplication. Experiments with engineered perMFE-1 variants demonstrate that the H1/I competence of domain A requires stabilizing interactions with domains D and E. The variant His-perMFE (residues 288-479)Delta, in which the domain C is deleted, is stable and has hydratase-1 activity. It is proposed that the extreme C-terminal domain E in perMFE-1 serves the following three functions: (i) participation in the folding of the N-terminus into a functionally competent H1/I fold, (ii) stabilization of the dehydrogenation domains by interaction with the domain D and (iii) the targeting of the perMFE-1 to peroxisomes via its C-terminal tripeptide. << Less

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
