identification of ten types of HXs and TrXs synthesized by recombinant Escherichia coli expressing bacterial arachidonate 15-lipoxygenase and/or epoxide hydrolase using five polyunsaturated fatty acids (PUFAs). Of these, eight types were new. The discovery was due to the microbial enzymes with high activities for the same catalytic activities as those of human enzymes. We succeeded in the efficient, cost-effective
Hepoxilins(HXs)和trioxilins(TrXs)是脂质介质,可调节人体中痕量的多种生理过程。它们已经通过化学方法合成,其具有诸如低产率,副产物形成和使用有毒化学试剂的缺点。在这里,我们报告了由重组大肠杆菌合成的十种类型的HX和TrX的鉴定使用五个多不饱和脂肪酸(PUFA)来表达细菌花生四烯酸15-脂加氧酶和/或环氧化物水解酶。其中,有八种是新的。该发现是由于具有高活性的微生物酶具有与人类酶相同的催化活性。我们成功地将PUFA通过细胞高效,经济,环保地生物转化为9种HX和TrX,从而产生了大于10 g L -1的14,15-HXB 3和13,14,15-TrXB 3,转化率> 70%。我们的研究有助于医学上重要的脂质介体的环境友好合成。
