In certain aspects, the present invention provides methods for producing terminally hydroxylated alkenes and alkynes by contacting an unsaturated or saturated hydrocarbon substrate with a hydroxylase enzyme. Exemplary terminal hydroxylases useful for carrying out the methods of the invention exhibit strong selectivity towards one terminal carbon of a hydrocarbon substrate and include, but are not limited to, non-heme diiron alkane monooxygenases, cytochromes P450 (e.g., cytochromes P450 of the CYP52 and CYP153 family), as well as long chain alkane hydroxylases. In some embodiments, the terminally hydroxylated alkene or alkyne is further converted to a terminal alkenal. In certain embodiments, terminally hydroxylated alkenes and alkynes are useful as insect pheromones which modify insect behavior. In other embodiments, terminally hydroxylated alkenes and alkynes are useful intermediates for producing pheromones via acetylation or oxidation of the alcohol moiety.
在某些方面,本发明提供了一种通过将不饱和或饱和的碳氢基质与一种羟化酶酶接触来生产端羟基化烯烃和炔烃的方法。用于执行本发明方法的示例端羟化酶对碳氢基质中的一个端碳具有强选择性,包括但不限于非血红素二铁烷烃单加氧酶、细胞色素P450(例如CYP52和CYP153家族的细胞色素P450)以及长链烷烃羟化酶。在某些实施例中,端羟基化的烯烃或炔烃进一步转化为端烯醛。在某些实施例中,端羟基化的烯烃和炔烃可用作改变昆虫行为的昆虫信息素。在其他实施例中,端羟基化的烯烃和炔烃是通过醋酸化或氧化醇基团来产生信息素的有用中间体。
