    摘要:
    近年来,酰基肉碱已成为诊断线粒体脂肪酸β-氧化(mFAO)和支链氨基酸氧化障碍的重要生物标志物,前提是它们反映了潜在的毒性酰基辅酶A物种,在线粒体内积累在酶嵌段的上游。但是,这些中间体的起源仍然知之甚少。肉碱航天飞机成员肉碱棕榈酰转移酶2(CPT2)可能参与了线粒体内由积累的酰基CoA代谢产物合成的酰基肉碱。为了解决这个问题,本文研究了CPT2的底物特异性概况。将表达人CPT2的啤酒酵母匀浆与饱和和不饱和的C2-C26酰基辅酶A和支链氨基酸氧化中间体孵育。通过ESI-MS / MS对产生的酰基肉碱进行定量。我们显示CPT2与中等(C8-C12)和长链(C14-C18)酰基辅酶A酯具有活性,而实际上未发现短链和长链酰基辅酶A或支链氨基具有活性酸氧化中间体。还发现反式-2-烯酰基-CoA中间体是CPT2的不良底物。进行的抑制研究表明,trans-2-C16:1-CoA可以作为CPT2的竞争性抑制剂(K(i)为18

  • Leaky β-Oxidation of a trans-Fatty Acid

    The degradation of elaidic acid (9-trans-octadecenoic acid), oleic acid, and stearic acid by rat mitochondria was studied to determine whether the presence of a trans double bond in place of a cis double bond or no double bond affects beta-oxidation. Rat mitochondria from liver or heart effectively degraded the coenzyme A derivatives of all three fatty acids. However, with elaidoyl-CoA as a substrate, a major metabolite accumulated in the mitochondrial matrix. This metabolite was isolated and identified as 5-trans-tetradecenoyl-CoA. In contrast, little or none of the corresponding metabolites were detected with oleoyl-CoA or stearoyl-CoA as substrates. A kinetic study of long-chain acyl-CoA dehydrogenase (LCAD) and very long-chain acyl-CoA dehydrogenase revealed that 5-trans-tetradecenoyl-CoA is a poorer substrate of LCAD than is 5-cis-tetradecenoyl-CoA, while both unsaturated acyl-CoAs are poor substrates of very long-chain acyl-CoA dehydrogenase when compared with myristoyl-CoA. Tetradecenoic acid and tetradecenoylcarnitine were detected by gas chromatography/ mass spectrometry and tandem mass spectrometry, respectively, when rat liver mitochondria were incubated with elaidoyl-CoA but not when oleoyl-CoA was the substrate. These observations support the conclusion that 5-trans-tetradecenoyl-CoA accumulates in the mitochondrial matrix, because it is less efficiently dehydrogenated by LCAD than is its cis isomer and that the accumulation of this beta-oxidation intermediate facilitates its hydrolysis and conversion to 5-trans-tetradecenoylcarnitine thereby permitting a partially degraded fatty acid to escape from mitochondria. Analysis of this compromised but functional process provides insight into the operation of beta-oxidation in intact mitochondria.
