two diterpene cyclases from streptomycetes—one with an unknown product that was identified as the spirocyclic hydrocarbon spiroviolene and one with the known product tsukubadiene—were investigated in detail by isotope labeling experiments. Although the structures of the products were very different, the cyclization mechanisms of both enzymes proceed through the same initial cyclization reactions, before
通过同位素标记实验详细研究了链霉菌中的两种二萜环化酶的机理,一种是未知产物,被鉴定为螺环烃螺环戊烯,另一种是已知的tsukubadiene。尽管产物的结构非常不同,但是两种酶的环化机理都是通过相同的初始环化反应进行的,然后才趋向于各个产物,这反映在酶的密切系统发育关系中。
