  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.

  亚油酸双键水合酶为关键酶，将亚油酸生物转化为羟基脂肪酸和羧酸

  摘要：

  AbstractHydroxy fatty acids are used as starting materials for the production of secondary metabolites and signalling molecules as well as in the manufacture of industrial fine chemicals. However, these compounds are usually difficult to produce from renewable biomass by chemical means. In this study, linoleate double bond hydratases of Lactobacillus acidophilus NBRC 13951 were cloned for the first time. These enzymes were highly specific for the hydration of the C‐9 or the C‐12 double bond of unsaturated fatty acids (e.g., linoleic acid). Thereby, the enzymes allowed the selective production of hydroxy fatty acids such as 13‐hydroxy‐cis‐9‐octadecenoic acid and 10‐hydroxy‐cis‐12‐octadecenoic acid from linoleic acid. In addition, the hydroxy fatty acids were further converted into industrially relevant carboxylic acids (e.g., 12‐hydroxy‐cis‐9‐dodecenoic acid, α,ω‐tridec‐9‐enedioic acid) and lactones (i.e., δ‐decalactone, γ‐dodecelactone) via whole‐cell biocatalysis using an enzyme cascade. This study thus contributes to the preparation of hydroxy fatty acids, unsaturated carboxylic acids, and lactones from renewable unsaturated fatty acids.magnified image
