• CYP505E3: A Novel Self‐Sufficient ω‐7 In‐Chain Hydroxylase

  The self‐sufficient cytochrome P450 monooxygenase CYP505E3 from Aspergillus terreus catalyzes the regioselective in‐chain hydroxylation of alkanes, fatty alcohols, and fatty acids at the ω‐7 position. It is the first reported P450 to give regioselective in‐chain ω‐7 hydroxylation of C10–C16 n ‐alkanes, thereby enabling the one step biocatalytic synthesis of rare alcohols such as 5‐dodecanol and 7‐tetradecanol

  来自土曲霉的自给自足的细胞色素P450单加氧酶CYP505E3催化ω-7位烷烃，脂肪醇和脂肪酸的区域选择性链内羟化反应。这是第一个报道的P450，具有C10–C16 n的区域选择性链内ω-7羟基化作用链烷烃，从而一步一步生物催化合成稀有醇（如5-十二烷醇和7-十四烷醇）。它显示出一个甲基末端对第八个碳原子的区域选择性超过70％，并且对癸烷（TTN≈8000）和十二烷（TTN≈2000）的活性很高。CYP505E3可用于通过两种途径合成高价值风味化合物δ-十二内酯：1）将十二烷酸转化为5-羟基十二烷酸（区域选择性为24％），在低pH内酰胺酶下可转化为δ-十二内酯，以及2）转化将1-十二烷醇转化为1,5-十二烷二醇（55％的区域选择性），可以通过马肝醇脱氢酶将其转化为δ-十二烷内酯。

  studies on the characterization of fatty acid hydroxylases. Three novel potential fatty acid hydroxylases (CYP109D1, CYP264A1, and CYP266A1) were used for detailed characterization. One of them, CYP109D1 was able to perform subterminal hydroxylation of saturated fatty acids with the support of two autologous and one heterologous electron transfer system(s). The kinetic parameters for the product hydroxylation

  提出了对纤维素酶Soce56的完整细胞色素P450补体（CYPome）进行的首次系统研究，该酶是重要的次生代谢产物的生产者，具有迄今为止最大的细菌基因组序列。我们描述了由21个推定的P450基因组成的Soce56细胞色素P450补体的生物信息学分析。由于脂肪酸在黏菌的复杂生命周期中起着关键作用，因此我们将研究重点放在了脂肪酸羟化酶的表征上。三种新颖的潜在脂肪酸羟化酶（CYP109D1，CYP264A1和CYP266A1）用于详细表征。其中之一，CYP109D1能够在两个自体和一个异源电子转移系统的支持下进行饱和脂肪酸的亚末端羟基化反应。

• Facile determination of the absolute stereochemistry of hydroxy fatty acids by GC: application to the analysis of fatty acid oxidation by a P450BM3 mutant

  The determination of the absolute stereochemistry of hydroxy fatty acid methyl esters as their (S)-ibuprofen esters is possible via standard gas chromatographic techniques. Analyses of various racemic and nonracemic standards and mixtures from enzymic oxidation show excellent resolution of the resultant diastereomers, with the (S,S)-diastereomers eluting first in all cases studied. The stereochemistry of the oxidation of dodecanoic acid by P450(BM3), which has not been previously reported, was determined by this method and indicated a preference for (R)-hydroxylation. The sensitivity of this technique allows the analysis of very small quantities of product, which has revealed that the oxidation of dodecanoic and hexadecanoic acids by the T268A mutant of P450(BM3) display the same stereochemical efficiency and produce (R)-hydroxy fatty acids in the same manner as wildtype P450(BM3), despite the poor coupling efficiency of these substrates. This stereochemistry implies that hydroxylation catalysed by the T268A mutant of P450(BM3) occurs through residual levels of the normal hydroxylating species. (c) 2007 Elsevier Ltd.
