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。
