Function
function
Medium-chain specific acyl-CoA dehydrogenase is one of the acyl-CoA dehydrogenases that catalyze the first step of mitochondrial fatty acid beta-oxidation, an aerobic process breaking down fatty acids into acetyl-CoA and allowing the production of energy from fats. The first step of fatty acid beta-oxidation consists in the removal of one hydrogen from C-2 and C-3 of the straight-chain fatty acyl-CoA thioester, resulting in the formation of trans-2-enoyl-CoA. Electron transfer flavoprotein (ETF) is the electron acceptor that transfers electrons to the main mitochondrial respiratory chain via ETF-ubiquinone oxidoreductase (ETF dehydrogenase). Among the different mitochondrial acyl-CoA dehydrogenases, medium-chain specific acyl-CoA dehydrogenase acts specifically on acyl-CoAs with saturated 6 to 12 carbons long primary chains.
Catalytic activity
- oxidized [electron-transfer flavoprotein] + hexadecanoyl-CoA + H+ = (2E)-hexadecenoyl-CoA + reduced [electron-transfer flavoprotein]This reaction proceeds in the forward direction.
- hexanoyl-CoA + oxidized [electron-transfer flavoprotein] + H+ = (2E)-hexenoyl-CoA + reduced [electron-transfer flavoprotein]This reaction proceeds in the forward direction.
- octanoyl-CoA + oxidized [electron-transfer flavoprotein] + H+ = (2E)-octenoyl-CoA + reduced [electron-transfer flavoprotein]This reaction proceeds in the forward direction.
- pentanoyl-CoA + oxidized [electron-transfer flavoprotein] + H+ = (2E)-pentenoyl-CoA + reduced [electron-transfer flavoprotein]This reaction proceeds in the forward direction.
- tetradecanoyl-CoA + oxidized [electron-transfer flavoprotein] + H+ = (2E)-tetradecenoyl-CoA + reduced [electron-transfer flavoprotein]This reaction proceeds in the forward direction.
- decanoyl-CoA + oxidized [electron-transfer flavoprotein] + H+ = (2E)-decenoyl-CoA + reduced [electron-transfer flavoprotein]This reaction proceeds in the forward direction.
- dodecanoyl-CoA + oxidized [electron-transfer flavoprotein] + H+ = (2E)-dodecenoyl-CoA + reduced [electron-transfer flavoprotein]This reaction proceeds in the forward direction.
