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,本发明提供了通过使不饱和或饱和烃底物与羟化酶接触来生产末端羟化的烯烃和炔烃的方法。用于实施本发明方法的典型末端羟化酶对烃底物的一个末端碳具有强选择性,包括但不限于非血红素二铁烷烃单氧化酶、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。在某些实施方案中,末端羟化的烯或炔进一步转化为末端烯醛。在某些实施方案中,末端羟基化的烯烃和炔烃可用作昆虫信息素,改变昆虫的行为。在其他实施方案中,末端羟基化的烯烃和炔烃是通过乙酰化或氧化醇分子生产信息素的有用中间体。
