Enzymatic synthesis of cyclic triterpenes

Natural Product Reports, 2007
This review covers recent advances in the chemistry and enzymology of squalene cyclase and oxidosqualene cyclase. The enzymatic cyclizations of squalene and oxidosqualene are the most remarkable steps in the biosynthesis of sterols and triterpenes. The polyenes are converted to various polycyclic triterpenes by different enzyme systems employing only ...
