Molecular cloning and functional expression of a multifunctional triterpene synthase cDNA from a mangrove species Kandelia candel (L.) Druce

An oxidosqualene cyclase homologue was cloned from Kandelia candel (L.) Druce, and identified as a multifunctional triterpene synthase able to produce lupeol, β-amyrin and α-amyrin in a 2:1:1 ratio by expression in the mutant yeast strain GIL77.
