  Enzymatic Desaturation of Fatty Acids:  Δ¹¹ Desaturase Activity on Cyclopropane Acid Probes

  摘要：

  The formation of methylenecyclopropanes by enzymatic desaturation of 11-cyclopropylundecanoic acid (1) and its disubstituted derivatives cis- and trans-3-5 has been investigated using the Delta(11) desaturase of Spodoptera littoralis as model enzyme. Gas chromatography coupled to mass spectrometry analyses of methanolyzed lipidic extracts from tissues incubated with each probe revealed that all the cyclopropyl fatty acids were transformed into the corresponding 11-cyclopropylidene acids, except for compound trans-5 (5b), which was not desaturated at C11. The formation of methylenecyclopropane 9 as the only reaction product from 1 indicates that a potential radical intermediate is too short-lived to allow rearrangement reactions. Information on the Delta(11) desaturase substrate binding domain is provided considering the cyclopropyl probes 3-5 as conformationally restricted analogues of the straight-chain substrates.

• Substrate specificity of acetyltransferase and reductase enzyme systems used in pheromone biosynthesis by Asian corn borer,Ostrinia furnacalis

  tested fatty alcohols indicated that the acetyltransferase has a low substrate specificity. Most of the corresponding tetradecenoic acids could also be converted to the respective acetates. However, very different conversion rates among the tested fatty acids demonstrated that the reductase system has a higher substrate specificity than the acetyltransferase. The conversion rates of mostE isomers were

  通过局部应用信息素腺体的前体，在体内研究了乙酰转移酶和还原酶系统在信息素生物合成中使用的 Ostrinia furnacalis (Lepidoptera: Pyralidae) 的底物特异性。每个十四烯醇，双键位置（从 7 到 13）和双键的几何形状不同，都被乙酰转移酶转化为相应的乙酸盐。所有测试的脂肪醇转化率的相似性表明乙酰转移酶具有低底物特异性。大多数相应的十四碳烯酸也可以转化为相应的乙酸酯。然而，测试的脂肪酸之间非常不同的转化率表明还原酶系统比乙酰转移酶具有更高的底物特异性。大多数 E 异构体的转化率高于相应的 Z 异构体的转化率，但 (Delta)-11-十四碳烯酸除外，其中更多的 Z 异构体转化为产物。饱和十四烷酸以高速率转化为相应的乙酸盐；较短的同系物十三烷酸的转化率较低 (56%)，而较长的同系物十五烷酸和十六烷酸各自的乙酸酯的转化率是微不足道的 (<5%)。本研究的结果表

  Cytochrome P450 from Bacillus megaterium catalyses the diastereoselective hydroxylations of 13-hydroxymyristic acid, to predominantly erythro-12,13-dihydroxymyristic acid, and of 12-hydroxymyristic acid to give predominantly threo-12,13-dihydroxymyristic acid, in reactions that are stereocomplementary and with considerable potential application in biotransformations.

Their structures were proposed on the basis of spectroscopic analysis and confirmed by chemical synthesis. They possess a novel α,α-bispyrone skeleton modified with long carbon chains. Both could be formed from two different polyketide chains through a
