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

  摘要：

  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.

  Products of Cytochrome P450_BioI (CYP107H1)-Catalyzed Oxidation of Fatty Acids

  摘要：

  [GRAPHICS]Oxidation of tetradecanoic and hexadecanoic acids by cytochrome P450(Biol) (CYP107H1) produces mainly the 11-, 12-, and 13-hydroxy C-14 fatty acids and the 11- to 15-hydroxy C-16 fatty acids, respectively. In contrast to previous reports, terminal hydroxylation is not observed. The enantiospecificity of fatty acid hydroxylation by P450(Biol) was also determined, and the enzyme was shown to be moderately selective for production of the (R)-alcohols.

  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。

  The biocatalytic hydroxylation of fatty acids is an appealing reaction, but the generation of over-oxidation by-products and the lack of selectivity hampers its transfer to industry. Now a highly selective and efficient peroxygenase has been engineered for the production of hydroxy fatty acids through a synthetic procedure that can be rapidly adapted to the preparative scale.

  脂肪酸的生物催化羟基化是一个吸引人的反应，但过度氧化副产物的产生和选择性的缺乏阻碍了它向工业的转移。现在，一种高选择性和高效的过氧化酶已被设计用于通过可快速适应制备规模的合成程序来生产羟基脂肪酸。
