Gene Summary
Mitochondrial trifunctional protein α subunit (Mtpα) encodes a subunit of the mitochondrial trifunctional protein. It possesses 3-enoyl-CoA hydratase and 3-hydroxyacyl-CoA dehydrogenase activities, which catalyze the second and third steps,respectively, of the β-oxidation of long-chain fatty acids.

Model Confidence:
  • Very high (pLDDT > 90)
  • Confident (90 > pLDDT > 70)
  • Low (70 > pLDDT > 50)
  • Very low (pLDDT < 50)

AlphaFold produces a per-residue confidence score (pLDDT) between 0 and 100. Some regions with low pLDDT may be unstructured in isolation.
