Mitochondrial trifunctional protein

Schematic demonstrating mitochondrial fatty acid beta-oxidation and effects of long-chain 3-hydroxyacyl-coenzyme A dehydrogenase deficiency, LCHAD deficiency

Mitochondrial trifunctional protein (MTP) is a protein attached to the inner mitochondrial membrane which catalyzes three out of the four steps in beta oxidation. MTP is a hetero-octamer composed of four alpha and four beta subunits:

The three functions are 2-enoyl coenzyme A (CoA) hydratase, long-chain 3-hydroxy acyl-coenzyme A dehydrogenase and long-chain 3-ketoacyl CoA thiolase.[1]
