Metabolite Identification
Common Name(2E)-Octenoyl-CoA
Description(2E)-Octenoyl-CoA is the main metabolite produced in medium-chain acyl-CoA dehydrogenase (EC 1.3.99.3, MCAD) deficiency; however the product of the enzymatic reaction is not directly detected in several methods for screening of inborn errors of fatty acid oxidation. In order to aid the timely follow-up of screening results that suggest abnormalities in MCAD, rapid and simple confirmatory tests for the enzyme activity and/or gene mutation analysis should be available. Medium-chain fatty acyl-CoA dehydrogenase (MCAD) catalyzes the conversion of different chain length fatty acyl- CoAs into their corresponding trans-enoyl-CoA moieties via two consecutive sequences of steps. The first step involves the concerted abstraction of a proton and a hydride ion from the a- and 8-carbon chains of the fatty acyl-CoA substrates, concomitant with the reduction of the enzyme (E)-bound FAD to FADH2. The reoxidation of EFADH2, to propagate further rounds of catalysis, is accomplished via transfer of electrons to a variety of organic electron acceptors; the natural electron acceptor for this process, under physiological conditions, is the electron-transferring flavoprotein. Of the different chain length fatty acyl-CoA substrates, octanoyl-CoA/octenoyl-CoA have been known as the most efficient (and physiological) substrates for the medium-chain fatty acyl-CoA dehydrogenase (MCAD)-catalyzed reaction.

Specific function:
Catalyzes the desaturation of acyl-CoAs to 2-trans-enoyl-CoAs. Isoform 1 shows highest activity against medium-chain fatty acyl-CoAs and activity decreases with increasing chain length. Isoform 2 is active against a much broader range of substrates and shows activity towards very long-chain acyl-CoAs. Isoform 2 is twice as active as isoform 1 against 16-hydroxy-palmitoyl-CoA and is 25% more active against 1,16-hexadecanodioyl-CoA.

Transporters

General function:
Lipid transport and metabolism
Specific function:
Involved in translocation of long-chain fatty acids (LFCA) across the plasma membrane. The LFCA import appears to be hormone-regulated in a tissue-specific manner. In adipocytes, but not myocytes, insulin induces a rapid translocation of FATP1 from intracellular compartments to the plasma membrane, paralleled by increased LFCA uptake. May act directly as a bona fide transporter, or alternatively, in a cytoplasmic or membrane- associated multimeric protein complex to trap and draw fatty acids towards accumulation. Plays a pivotal role in regulating available LFCA substrates from exogenous sources in tissues undergoing high levels of beta-oxidation or triglyceride synthesis. May be involved in regulation of cholesterol metabolism. Has acyl-CoA ligase activity for long-chain and very-long-chain fatty acids
