  通过漆酶催化的氧化裂解从新型不饱和脂肪酸生产二羧酸。

  摘要：

  由于全球变暖和石油储备的枯竭，建立可再生的生物燃料和化学产品是可取的。癸二酸（癸二酸）是6,10尼龙的材料，是由蓖麻油酸（一种碳中性材料）生产的，但由于能源需求，该工艺不环保。漆酶催化脂肪酸的氧化裂解被用于生产二羧酸，使用参与植物乳杆菌中不饱和脂肪酸饱和代谢的羟基和羰基脂肪酸。具有一个在碳-碳双键附近的官能团的羟基或氧代脂肪酸被漆酶裂解在碳-碳双键，羟基或羰基上，并转化为二羧酸。8小时后，由1.生成0.58 mM的癸二酸。6 mM的10-氧代-顺式-12，顺式-15-十八碳二烯酸（αKetoA），转化率为35％（mol / mol）。这种漆酶催化的酶促工艺是一种从生物质衍生的脂肪酸生产二羧酸的有前途的方法。

  Characterization of hydroxy fatty acid dehydrogenase involved in polyunsaturated fatty acid saturation metabolism in Lactobacillus plantarum AKU 1009a

  摘要：

  Hydroxy fatty acid dehydrogenase, which is involved in polyunsaturated fatty acid saturation metabolism in Lactobacillus plantarum AKU 1009a, was cloned, expressed, purified, and characterized. The enzyme preferentially catalyzed NADH-dependent hydrogenation of oxo fatty acids over NAD(+)-dependent dehydrogenation of hydroxy fatty acids. In the dehydrogenation reaction, fatty acids with an internal hydroxy group such as 10-hydroxy-cis-12-octadecenoic acid, 12-hydroxy-cis-9-octadecenoic acid, and 13-hydroxy-cis-9-octadecenoic acid served as better substrates than those with alpha- or beta-hydroxy groups such as 3-hydroxyoctadecanoic acid or 2-hydroxyeicosanoic acid. The apparent Km value for 10-hydroxy-cis-12-octadecenoic acid (HYA) was estimated to be 38 mu M with a k(cat) of 7.6 x 10(-3) s(-1). The apparent K-m value for 10-oxo-cis-12-octadecenoic acid (KetoA) was estimated to be 1.8 mu M with a k(cat) of 5.7 x 10(-1) s(-1). In the hydrogenation reaction of KetoA, both (R)- and (S)-HYA were generated, indicating that the enzyme has low stereoselectivity. This is the first report of a dehydrogenase with a preference for fatty acids with an internal hydroxy group. (C) 2015 Elsevier B.V. All rights reserved.
