The present invention provides methods for catalyzing the conversion of an olefin to a compound containing one or more aziridine functional groups using heme enzymes. In certain aspects, the present invention provides a reaction mixture for producing an aziridination product, the reaction mixture comprising of an olefinic substrate, a nitrene precursor, and a heme enzyme. In other certain aspects, the present invention provides a method for producing an aziridination product comprising providing an olefinic substrate, a nitrene precursor, and a heme enzyme; and admixing the components in a reaction for a time sufficient to produce an aziridine product. In other aspects, the present invention provides heme enzymes including variants and fragments thereof that are capable of carrying out in vivo and in vitro olefin aziridination reactions. Expression vectors and host cells expressing the heme enzymes are also provided by the present invention.
本发明提供了利用血红素酶催化烯烃转化为含有一个或多个氮杂环丙烷官能团的化合物的方法。在某些方面,本发明提供了用于生产氮杂环丙烷产物的反应混合物,该反应混合物包括烯烃底物、氮烯前体和血红素酶。在其他某些方面,本发明提供了一种生产氮杂环丙烷产物的方法,包括提供烯烃底物、氮烯前体和血红素酶;并将这些组分混合在反应中,以产生氮杂环丙烷产物所需的时间。在其他方面,本发明提供了包括能够在体内和体外进行烯烃氮杂环丙烷化反应的血红素酶及其变体和片段。本发明还提供了表达载体和表达血红素酶的宿主细胞。
