We cloned a full-length cDNA of squalene synthase gene from Magnolia officinalis for the first time.
Prokaryotic expression showed that MoSQS mutant (MoSQSΔTM) could be expressed solubly in Escherichia coli Transetta (DE3).
MoSQSΔTM is functional and provided an important base for the study of triterpenoids biosynthesis in Magnolia officinalis.
