Mitochondrial trifunctional protein deficiency. Catalytic heterogeneity of the mutant enzyme in two patients.
Kamijo T., Wanders R.J., Saudubray J.-M., Aoyama T., Komiyama A., Hashimoto T.
We examined the enzyme protein and biosynthesis of human trifunctional protein harboring enoyl-CoA hydratase, 3-hydroxyacyl-CoA dehydrogenase, and 3-ketoacyl-CoA thiolase activity in cultured skin fibroblasts from two patients with long-chain 3-hydroxyacyl-CoA dehydrogenase deficiency.

We examined the enzyme protein and biosynthesis of human trifunctional protein harboring enoyl-CoA hydratase, 3-hydroxyacyl-CoA dehydrogenase, and 3-ketoacyl-CoA thiolase activity in cultured skin fibroblasts from two patients with long-chain 3-hydroxyacyl-CoA dehydrogenase deficiency. The following results were obtained. (a) In cells from patient 1, immunoblot analysis and pulse-chase experiments indicated that the content of trifunctional protein was < 10% of that in control cells, due to a very rapid degradation of protein newly synthesized in the mitochondria. The diminution of trifunctional protein was associated with a decreased activity of enoyl-CoA hydratase, 3-hydroxyacyl-CoA dehydrogenase, and 3-ketoacyl-CoA thiolase, when measured using medium-chain to long-chain substrates. (b) In cells from patient 2, the rate of degradation of newly synthesized trifunctional protein was faster than that in control cells, giving rise to a trifunctional protein amounting to 60% of the control levels. The 3-hydroxy-acyl-CoA dehydrogenase activity with medium-chain to long-chain substrates was decreased drastically, with minor changes in activities of the two other enzymes. These data suggest a subtle abnormality of trifunctional protein in cells from patient 2. Taken together, the results obtained show that in both patients, long-chain 3-hydroxyacyl-CoA dehydrogenase deficiency is caused by an abnormality in the trifunctional protein, even though there is a heterogeneity in both patients. << Less

Molecular characterization of mitochondrial trifunctional protein deficiency: formation of the enzyme complex is important for stabilization of both alpha- and beta-subunits.
Ushikubo S., Aoyama T., Kamijo T., Wanders R.J.A., Rinaldo P., Vockley J., Hashimoto T.
Mitochondrial trifunctional protein (TP) is an enzyme complex with three activities: enoyl-CoA hydratase, 3-hydroxyacyl-CoA dehydrogenase, and 3-ketoacyl-CoA thiolase.

Mitochondrial trifunctional protein (TP) is an enzyme complex with three activities: enoyl-CoA hydratase, 3-hydroxyacyl-CoA dehydrogenase, and 3-ketoacyl-CoA thiolase. Studies on defects in this enzyme in patients with TP deficiency suggest that there are two types of defect. Patients in group 1 have normal amount of cross-reacting material by immunoblot and lack only long-chain 3-hydroxyacyl-CoA dehydrogenase activity. Patients in group 2 have a trace amount of cross-reacting material, with all three activities being low. We identified three patients in group 2, and analysis was made at the cDNA level. In patient 2, there was a heterozygous 71-bp deletion at position 110-180 in the alpha-subunit. In patients 1 and 3, there was an abnormal beta-subunit; patient 1 had an A-788-to-G substitution, and patient 3 had G-182-to-A and G-740-to-A substitutions in each of separate alleles. This is the first demonstration of disease-causing mutations in the beta-subunit. cDNA-expression experiments in patients' fibroblasts, using a vaccinia virus system, and gel filtration analysis, using patients' fibroblasts, revealed that the existence of both normal alpha- and beta-subunits, and possibly their association, are important for stabilizing TP and that A-788-to-G substitution on the beta-subunit in patient 1 seems to interfere with the association, the result being a rapid decomposition of TP. << Less

Identification of the peroxisomal beta-oxidation enzymes involved in the degradation of long-chain dicarboxylic acids.
Ferdinandusse S., Denis S., Van Roermund C.W., Wanders R.J., Dacremont G.
Dicarboxylic acids (DCAs) are omega-oxidation products of monocarboxylic acids. After activation by a dicarboxylyl-CoA synthetase, the dicarboxylyl-CoA esters are shortened via beta-oxidation.

Dicarboxylic acids (DCAs) are omega-oxidation products of monocarboxylic acids. After activation by a dicarboxylyl-CoA synthetase, the dicarboxylyl-CoA esters are shortened via beta-oxidation. Although it has been studied extensively where this beta-oxidation process takes place, the intracellular site of DCA oxidation has remained controversial. Making use of fibroblasts from patients with defined mitochondrial and peroxisomal fatty acid oxidation defects, we show in this paper that peroxisomes, and not mitochondria, are involved in the beta-oxidation of C16DCA. Additional studies in fibroblasts from patients with X-linked adrenoleukodystrophy, straight-chain acyl-CoA oxidase (SCOX) deficiency, d-bifunctional protein (DBP) deficiency, and rhizomelic chondrodysplasia punctata type 1, together with direct enzyme measurements with human recombinant l-bifunctional protein (LBP) and DBP expressed in a fox2 deletion mutant of Saccharomyces cerevisiae, show that the main enzymes involved in beta-oxidation of C16DCA are SCOX, both LBP and DBP, and sterol carrier protein X, possibly together with the classic 3-ketoacyl-CoA thiolase. This is the first indication of a specific function for LBP, which has remained elusive until now. << Less
