描述
(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. (PMID: 16046200, 1390638, 8038175) [HMDB]. (2E)-Octenoyl-CoA is found in many foods, some of which are rapini, mung bean, tamarind, and peach.
